Inaccurate or offensive

Help me understand this rejection. Is there something I'm unaware of in the title that is offensive?
As I understand it, titles should be related but don't have to be a descriptive title.
I believe the character on the wall is called Big Blue

I think there's a bug giving the wrong rejection reason
Big Blue is the name of the printing company that printed and pasted the decal on the wall.
Was a current bug that I think almost all rejections had the same reason but during very minor maintenance breaks earlier today, they've removed the reject reasons so it just remains blank.
Interesting info. Cheers 👍
As for eligibility, its no different from any supervised kids playground
That explains why I didn’t get an agreement then! I accepted this one - I would love to hear from others why they rejected it (or why they would have rejected it) to help me improve my reviewing.
