Can't remove a photo that appears in the artist thumbnail for my personal music

I play guitar and upload my music into my Apple Music app on my desktop. I do not sell my music or engage with the iTunes store for profit. For some reason, the picture of someone is showing as the thumbnail for my name. Searching for my name in the iTunes store to try to find the photo being used doesn't find the rogue photo either. This photo is of person of different ethnicity than I am and it's annoying to see it every time I go to MY music in the app. I've uploaded my own photo using the info area for songs which appears to work temporarily, but the other photo comes back every time. I've tried putting my name together with no spaces, using initials, alternate spellings etc. but every time I do this, the same photo comes back. I just want to delete that random picture and put my own there but can't see how to do it.
