I can’t purchase new books

I went to buy the 3 volumes of Research and Debate and I tried to purchase them thru the bookcase at first and went to drop down the menu to the skills filter and there were only 4 skill books available. Also, only books that were previously purchased were available. I tried to delete the bookcases and repurchase them, repair the game, clear the cache, delete the UI files, start a new game, recover/restart the app, and the problem still persists. I don’t have any pictures and I also don’t know how long this has been an issue, I only noticed this a couple hours ago. I deleted any lots that I downloaded, from the gallery and like I stated before I’ve restarted the game/app/laptop many many times. I don’t use mods so that can’t be the issue but is there anything else I can do to try and fix this issue???
