Related record bundles don't hide with dependent field visibility. See Kress system:
They have requested:
Artists only have Related Art Objects
Institutions only have Related Art Objects and Related Distributions
Sellers only have Related Acquisitions and Related Documents
Others only have Related Documents
Two things are wrong here: (1) you need the "category" drop on the "related records" screen as it's what controls the dependent visibility. If it's not on the screen none of the dependent visibility settings are enforced. I've added it on the kress system by hand so you can see it working. When dependent visibility was added the person who wrote developed it (not me) built it this way. We could make it work where the drop-down was not required, but it'd be a bit of work.
(2) The dependent value settings weren't set properly for all categories. I've done that by hand too on the kress system so you can see how it works. We'll need to add these settings to the profile.
ok. I can try adding the category field to that screen and making it read-only. Hopefully she’ll be ok with it.
If she's not I can work on expanding what we have to not require it. But let's see...
