Images with pink background

I'm having problems removing items on photos with pink backgrounds, I get the message "The generated images were removed because they violate user guidelines." 

I don't know why but I suspect that the pink in my images is being flagged as skin but it's not, it's just a flower on a pink background.

Hopefully there will be some way to flag those images that are mistakenly flagged as violating user guidelines.

Thanks!
