Encryption job always failing

Hi all,

I just discovered this app and there is something I cannot get to work.
I create a job to sync folder A over folder B; then I have created a secure job to encrypt folder A and a second job to encrypt folder B.
Finally, I have created a script via GUI to perform those three job:
--> sync A over B
--> encrypt A
--> encrypt B
but and the script finish without encrypting files inside folder A and B and the log says that it is "impossible to decrypt" files

Am I making some mistake? It is a bug?

Thanks in advance
Roby
