Definitely a bug, thanks for reporting @LucaGiamminonni . However, I'm scheduling this for 7.1, as this bug is very low priority until #761 is implemented (also scheduled for 7.1). Currently, this "Content Source" tab is very minimal (only changes settings) as described in #506.

That said, if the fix is small here, I'm not against having this completed early -- it's just low priority currently. This will also need estimation.

I think this has already been fixed as part of #961. I encountered it while testing and thought it was an issue with the PR.

[tdonohue]

@artlowel is correct. I've verified that this bug is fixed by #961. I'll update this ticket so that it'll close when #961 is merged.
