Show Taxonomy column on Post Types Issue

Hello,

Are you aware of anything that could prevent “Show Taxonomy column on Post Types” option from working?

I have a post type called Case Studies.

I have 4 taxonomies connected to this post type.

I recently created the latter 3, the first existed for years.

All have the option “Show Taxonomy column on Post Types” turned on.

Only the first taxonomy created years ago actually shows the column.

I tried checking “Screen Options” and the new three aren’t in here.

Is there another setting that can stop it from working? I tried a bunch of stuff and copied another site’s settings and they still don’t show, it’s perplexing me.

Any ideas?

Thanks in advance.
