The reason why this happens is because the verification screenshot is attached as system picture. For the competition, we have an automatic check that looks if a verification screenshot is attached to the submission.
For XTU it's a bit of a pickle because the submission process is typically via the XTU software, which doesn't give the option to add a verification screenshot. For competitions, a manual submission is better because the form gives you the option to add a verification screenshot.
Let me fix the submission for ya, Bassplayer.
