My FB game just recently got rejected for two reasons. The first I fixed, but I just can't see to figure out what they mean by the second, and I was hoping someone else got the same issue and did know what they meant.
The remaining error is:

All I know is that the rejection has something to do with the cover image, not the icons or the screenshots.
The web preview of my game looks like this now:
Please let me know what to do to get approved.
