This is not surprising for several reasons. One of which is Dalle simply can't count. Asking it for 3 of anything will give questionable results. Dalle also doesn't understand relations between objects. It will fail on anything of the form A on top of B. Indeed usually the order of words is irrelevant to the output. Lastly, features of certain length scales (such as lines below some thinness) are always garbled. Try generating the standard face cards in a deck of playing cards to see what I mean.
