Kits Disappearing When in Gallery

Recently, after the last download, whenever I go into the Gallery to look for a lot, build, or Sim. All of the kits are unchecked. I own every kit except the Sponge Bob kits. When selecting, I kept getting a notice that not all items were available if I download the items. When I checked, I saw that all kits were unselected. I clicked every kit and the message went away. I placed a lot, then went to look for another, all the kits were unchecked again. 

I removed all my mods and cc. The problem is continuing. I'm on PC, completely up to date. 

It keeps happening. Is this happening to anyone else?
