mapping data source for a dataset doesn't work when having multiple instances of it

Hello everyone! hope anyone faced this problem and can help us!

at the time of mapping a data source for a dataset we found it doesn't work as expected.

Our data source is an SQL Server and we have created 3 test connections for it (with different configuration like SSO, Windows, etc)

So, when we try to map we have multiple options, like the test example below. The thing is that it ALWAYS takes the first one on the list, no matter which one we select and apply. and the list it's order by the data they were created, so the oldest one is listed first. any ideas? appreciate!
