Latest UltimatePOS item/category scrolldown issue

Hi everyone, I’ve noticed that in the latest version of UltimatePOS, when you switch between categories and then scroll down through the items, something happens, but navigation between categories and items no longer works. Has this happened to anyone else? How did you fix it?
