[GAMEPLAY] Cannot sell items in my inventory bc of shop

I discovered this bug yesterday as I was playing my games and I decided I would see if it would change and it hasn't so I was asked to report it here. I cannot sell the items in my inventory or even see them, or my champ/abilities once I open the in-game store. I tried moving the store around and in different places, but I can't change the size of it. I don't know if it is a bug, but I haven't changed anything with my screen resolution or the game resolution. I literally just hopped on and my store was messed up. I tried opening and closing the game repeatedly in game as well to see if it would help and it didn't. I do not have this issue on the gaming computers I have at school. This is also the new client, if that helps.

Thanks for any assistance.
