I'm not sure how best to help. As you can see in the attached image, I added the Custom Group tab, created an entry called "Test", and I right-clicked it, and it's selected.

Yes, I did the same. Created an entry called 'test' and deleted that, no problems. But I can't delete the actual 'Custom Group' itself.

But - perhaps it's not meant to be deleted. It's just when I see it in the Settings I though I would be able to remove it, set it back to there being no custom group.

I have hidden it. I think perhaps that's what is to be done and I was overthinking.

Sorry to have given you all this trouble.
