Problem solved.

I had "Hide categories" set to 'yes', and only changing that one solved the entire problem.
Didn't think that setting would affect categories from the same parent, but apparently it did...

Thanks for all your help! I really appreciate it!

But alas, now I seem to have hit a wall.

I'd like to have the 'categories'-plugin display only ...
