bundle bug

Hello, so on the ea app when go to the sims and there is an option where you can bundle an save on packs. when i click this feature it only shows me packs that I've bought, knowing that i still don't all of the 100 packs that the sims has currently for sale. idk if it my pc that glitching or the ea app. as shown on the picture below. it only shows me packs that I've bought not own.
