Hey, so I was trying to post an image for a portal prompt, but it gave me this error: imagecreatefrompng(): gd-png: libpng warning: iCCP: known incorrect sRGB profile

It still appears on my profile, and I think I tried 2 times, but I can't delete them. When I try it says "Parent not found".

They are these:

What is wrong with the image? And why can't I delete the duplicates?

Thanks!
