That's just a thing that happens with profile tags. It happens on the wikis I've placed them as well. So far, the only way I think you would get rid of that glitch is to ask fandom to change the promoted users tags officially, but you'd need a good reason for that.

What about the UserTags plugin? Is it the same?

I personally don't use those, as ProfileTags is way easier to manage.

UserTags is extremely complicated, but I believe it will cause the same glitch, as the problem is not with the code, because the page loads before any imported code.

The issue is that custom scripts on are reloaded each time you reload a page, and not as the first priority. So I don't think there's a proper way around it.

Damn it, fandom.

I think they had this feature in the past - to hide your user group tag - but removed it.

There is a feature to hide them, but what is probably happening is that the regular tags show up as part of the profile, and then ProfileTags loads in and hides them and inserts its own tags. You could try seeing if there's a reason why it's taking a while to load (eg load order, slow network, etc), and/or use CSS to hide the regular tags.

Hmm. Interesting, @Sophiedp. But will using CSS hide the regular tags for everyone in the site as well?
