Owned DLC Missing Items In Game

I have been encountering an error message in game that says "Content Not Installed." It says that "Purchased or other content used in this gallery item is not installed. If you place it now, you will not see the uninstalled content. Do you want to place this household/lot." 

I have a lot of expansion packs, stuff packs, game packs, and a few kits, but do not utilize any CC or Mods at all. The items that I'm having an issue with are all households or lots that I made myself with all the packs that I own. When viewing it in my Gallery, under the most recent updates, it now has two tabs at the bottom. The left one for "show used items from these packs" and displays all my packs that I own and that are downloaded. The right one says "show used items" and has a red X over a few items that I just chose in CAS with no problem.

I tried making a sim and saving it with 0 DLC content and didn't have the error message. I did it again with just 1 random item from a DLC and was given the message. Not every time I do this will it show the red X, but I always get this message when trying to place my own content from the Gallery into a save.  

I waited until the new updates and downloaded those. I used the EA app to repair all content. I cleared the cache. Tried closing out the game and starting it up again. I'm sure there's other things I haven't tried that might work, but I haven't seen a lot of people commenting about this particular issue.
