If the view you're using is baked into the custom skin, it might be that the ID used for the Poss won and alost per 90 is wrong and therefor can't show data
i just tested and adding them to a view from within the game works fine.
So in any case, yo can always try and delete them from your view and re-add them to see if that fixes your issue
also remember that players need to have played enough time for the per 90 to start showing data
