Creating personas broke the site

As the title says, I tried to create a new persona other than the original one I used when I first started and now I can't chat with new bots because it doesn't allow me to choose any of the personas, it doesn't allow me to delete the new persona and instead of getting deleted it multiplies (I got 9 of the same persona) and it basically made the site unusable other than chatting the bots I've already chatted with. Is there a way to fix this? Am I the only one having this issue?
