Synchronization Editor: Test connection failure after import sync project


1IM 8.1 (2019-01-21-108).

I have imported Native Database sync project to PostgreSQL database (via .projshell file)

When I click Test button (In Target System) for check connection to the PostgreSQL database see error: "Data source name not found and no default driver specified".
In parameters window I see Driver is "{PostgreSQL ANSI}". If I remove " " the Test connection success.

My changes not saving and next time I have got error again.

In source 1IM all ok. 

Any ideas?
