the champions appear to me as if I did not have them

greetings, today when I opened the game and go to the collection (to be more exact where it says champions) to see the list of champions I have appear as if I had none (which should not that I buy them all) also when I am in the selection of champions before starting a game when I want to select a skin of the champion that selects tells me that because I do not have the champion I do not have access to said skin (example: I'm going to select ekko and I want to use the skin of ekko academy but it tells me that I can not because as I do not have ekko I can not use the skin, which I should not because I have both ekko and said skin). I need help to solve this bug
