Ok- got it to work. I think the “taxonomy term” filter type might have gone the way of the dodo in a recent release, replaced with taxonomy = all (if you want the field for all taxonomies). When I chose this, my custom fields appeared.
Also, you can filter for the fields to only appear on certain terms with the post taxonomy = whatever category you choose.
If you are still having issues and it is not appearing, see if another field group is already targeting those taxonomies or specific categories. I’m not for sure the rules on multiple field groups to the same targeted whatever, and there could always be a bug.
But I think the above will solve what ails ye. Let me know if it doesn’t.
