Base Game Toilet Registering As Island Living?

Trying to do a limited build using the new Adventure Awaits Pack and Base Game Only. Upon trying to use the Base Game Toilet - Atlantis Plumbtrap, my game is registering it as Island Living item. Therefore trying to load it to the gallery as an Adventure Awaits and Base Game only build, it is showing Adventure Awaits as well as Island Living. I saved the lot in my gallery, to try to figure this out, and when I click on the Island Living icon, to see what items were used from the pack, there is the option to "see what is used", and when clicked there are NO items listed; and mind you it is showing me "see items listed" under CAS section, and not down on the build mode section. In order to figure out what the item was, I had to save each room singularly. then hover over them to see what had the Island living item. then loaded into that room only and deleted items, and resaved the room until i could see what was the "Island Living" item. and it is telling me that it is the toilet. We visibly saw the symbol for island living show up overtop of the toilet, after NOT being there for multiple screen flips. and double checking myself, I researched all items for Island Living, and then searched the toilet name, and it shows it as supposing to be base game. so not sure why it is glitching as such. I was bugging out and do not have a screenshot where the island living icon was on the base game toilet. I was restarting things, and looking around in such confusion. but it wasn't there, then showed up, then went away.
