Issue: Profile changes don't show

I have customized my profile with different fonts and a background but it seems I am the only person who can see the changes (my senpai told me she doesn't see the changes, that it looks like the base profile). I made the customization, more or less, a week ago but didn't realized this bug till my senpai told me about it.

Thanks for the support in advance!

PS: I will put the pics of how I see it and how my senpai (and maybe other people) see it
