Server roster bug

I couldnt find anything about this anywhere, so this could already have a solution, but me and a few friends were messing around last night and at one point started changing one users name multiple times over and over. After about half an hour, everyone started noticing that the original name was still on the server. I decided to scroll around out of curiosity only to realize that her name began to multiply, until it had replaced everyone elses name in the roster. Ive tried to kick and re-invite her, restart discord, end the discord task, restart my computer, log into browser, and log into mobile. Every single client does the same thing. Its only on my server, and viewing other servers gives it a sort of "soft" reset, but upon going back and scrolling up and down a few times, it still multiplies her name again. This happened over 16 hours ago.
