Updating Header and Cover for Profile

I've been trying to change my header and cover on my MuseScore profile. However, when I go and refresh to make sure my changes have saved, they go back to the changes I had before and it's getting annoying. I can't tell if the changes saved for other people viewing my profile and it doesn't show on my end, or if they didn't save at all. Any idea on how to fix this? Please help a brother out.
