Hey,
Alright, so I’m happy to announce I’ve figured out the problem, and embarrassed to say it was all my fault, haha.
In functions.php I had a function set using pre get posts when a user performed a search query, allowing them to only return “movie” post types. I thought this was only affecting the front end, but it was actually affecting the entire site, backend and all. Once, I tweaked that code to basically only pre get posts for front end search queries, everything works as it should.
Stupid mistake on my part. But very happy to have this finally resolved.
