Compiling several list in sccreen is not working

I´m trying to create a group with 4 different types of categories, in order to do so without making them to big to scroll down , I set the limit of each list to four, but as soon as and only if I set the first category to four, the whole screen crashes and shows only for images randomly. If I do the same with the rest of the categories, everything works fine except that category.
I already deleted it and it won´t let me.
please help.
