Colums not as described

In the category section i have 4 columns selected. i have 4 categories listed. however, they are stacked on top of each other instead of side by side. then in the collection section i have 12 selected but the 2nd selection is not the same icon size as the others. ive tried different pics but its in the code showing a landscape layout instead of a square. the other 11 are all the same, just number 2 collection is shown as a different ratio lastly, are there able to have options under each product as for say different sizes available? thanks
