Batch Edit not working

Hello everyone,

I try to edit the credentials for all Connections.
I marke them all, click on Edit -> Batch Edit ->Edit General Settings -> Tools -> Override -> Use my Personal Credentials.
But after clicking on ok, nothing happens.
The connections still have "default" as Credentials.

I'm using the MS SQL Database with MS SQL Sever 2014

How can i fix that ?

Cheers

Alex
