[Closed] Mail Merge Wizard doesn't work properly

1. Step 1: Creation of a data source using LibreOffce Portable Calc

In a first step it's necessary to create a data source. For this creation you can use LibreOffce Portable Calc. In the following screenshot you can see a typical example of such a data source. I'll call the appropriate file "customers.ods". Please also note the bolded field names in the first row of this table (Salutation, FirstName, LastName, City, Postcode). The usage of these field names is very important in step 4 "Insert address block" of the "Mail Merge Wizard".

screenshot: customers

2. Step 2: Select starting document

After the start of the "Mail Merge Wizard" please let the selection "Use the current document" unchanged and click on the buttton "Next".

3. Step 3: Select document type

In this dialog window once again you let the selection "Letter" unchanged and click on the button "Next".

4. Step 4: Insert address block

In this dialog window you click on the button "Select Address List..." at the top on the right. Afterwards you click on the button "Add..." and chose the table named "customers.ods". Finally you click on the button "Ok".

Now you set a checkmark next to "This document shall contain an address block". Then select the second rimmed address block righthand.

Now you click on the button "Match Fields...". Then click on the downward-pointing arrow next to "Title" and choose the entry "Salutation".Then click on the downward-pointing arrow next to "First Name" and choose the entry "FirstName". Then click on the downward-pointing arrow next to "Last Name" and choose the entry "LastName". Then click on the downward-pointing arrow next to "Address Line 1" and choose the entry "Address". Then click on the downward-pointing arrow next to "City" and choose the entry "City". and finally click on the downward-pointing arrow next to "Zip" and choose the entry "Postcode".

Finally you can now click on the button "Next" at the bottom.

5. Step 5: Create salutation

In this dialog window please set checkmarks next to "This document should contain a salutation" and "Insert personalized salutation".

Then click on the downward-pointing arrow next to "Field Name" and choose the entry "Salutation". In the empty field next to "Field value" you write "Mrs.".

Finally you can now click on the button "Next" at the bottom.

6. Step 6: Adjust layout

This dialog window you can leave unchanged.

Finally you can now click on the button "Next" at the bottom.

7. Step 7: Edit document

This dialog window you can leave unchanged.

Finally you can now click on the button "Next" at the bottom.

8. Step 8: Personalize document

In this dialog window should now appear all the concrete address blocks. But unfortunately all the address blocks are disappeared. That's the bug!!

The full location of my installed LibreOffice Portable is:
C:\Portable Programme\PortableApps\LibreOfficePortable

Despite the removal of the value in the registrymodifications.xcu file the error I described above occurs again.

Here the content of this value: file:///C:/Portable Programme/Documents

As I have mentioned it in my original post, I got correct results with X-LibreOffice. For more transparency and simplification I can show it you with the help of TeamViewer.

I have forgot to mention, that I have used an older version of X-LibreOffice namely v4.0.4.2. Accordingly I have now downloaded the newest version of X-LibreOffice (v4.2.0.4) as a standalone version. And indeed I get now the same issues, which I described in my original post.
In summary, it can be clearly concluded, that in the program itself is a bug.

For this reason I have closed this reported bug.
