Gateway not recognized - and TWO lines for the same Oracle server appear in 'Gateway Connection'

Hi ladies and gents,

I have no idea why this is happening... So, I have this beautiful dataset with connections to an Oracle server (and other things).

I added one more query in the same server, and it won't recognize the gateway.

Like, in the first line, where you have that button to select the gateway, at status, after 'Running on...' it says 'select all datasources to use'. The status is in green.

Then, below, in the datasources, I have TWO lines with the same name: Oracle "server", and it won't let me 'Maps to' the server name. I mean, I click on the server name, and I can't click Apply.

Another weird thing: if I publish the same dataset with a DIFFERENT name, it works fine! One single line with the Oracle 'Server' too.

I don't want to switch to the new-name dataset, as I'll have to redirect all of the reports to it, and the users will lose their bookmarks (will they?).

I think it's a bug in our beloved Power BI...

Best,

Alice
