Trashley’s boxes and collections

I’m currently on my Super Sim save, where I’m also working on finding all of the household collections. I recently got the Business and Hobbies pack, and decided I wanted to give the new collections a go. I purchased a whole bunch of boxes from Trashley Reelperson, and noticed as I was opening them that I was finding a lot of collectables from other collections as well, such as marbles and feathers, which I haven’t done yet. However, when I go into my Household Collections, those items still aren't marked as found. I’ve tried taking them out of my sims inventory and putting them back in, and many other ways to get them to register as found, but it seems as they’re not even registering as belonging to my sim that opened the boxes. Is there a way to get them to register as being found by her?
