Desktop > Clean Up By > Size : The resulting arrangement makes no sense. Am I missing something?

If I run the action: Desktop > Clean Up By > Size : The resulting arrangement makes no discernible sense. Am I missing something? I have had this problem persist through many macOS updates. I do not know if it is just my computer, if I don't understand what's going on, or if this is a more common problem. It is only mostly arranged vertically by file type, but that doesn't make sense because there should not be a string of multiple folders in a row when various other files have sizes that should break that sequence up. The folders also aren't even in the right order. Finder's sort by size feature still works perfectly well. Desktop > Clean Up By : Also works perfectly fine for every other variable.
