Weird error with variables (3.1 build 31.Oct.) and equalize

Hello all,

There is a strange error that pops up when tying to sync with a network share.

The error is:
The source must exist
Toucan 3.1 must exist

The job looks like this:

Source:
@LocalF@\Files\Sync\

Destination:
@Remotehost-D@\Files\Sync\

Variables:
LocalF F:
Remotehost-D \\remotehost\d

Oddly enough, it shows the preview, both folder contents and does work with the path names instead of the variables. This is on Win7-64bit.

Help/bug?
