Artistic Prodigy Bug, 4/5 drawings.

XBOX.

No matter how many drawings I do I can't get this challenge to complete.   No idea what I could be doing wrong or why it won't complete.  The bug has been reported before and I've read and tried different solution like drawing them in alphabetical order or drawing them in the order they came up for creativity levels.  I've hung them on the wall, I've kept them in the childs inventory. .. this is frustrating.  I'm at creativity level 10 and have all pictures available. I've tried this 5 times and have 5 of each picture...monster, vehicle, people, shapes, animal.   Does anybody have any solutions at all?
