visiting court.kleros.io makes it ask the wallet to add stPNK, no matter if it has already been added. I don't know why it's the case. Might be a Rabby bug, since Rabby shouldn't be showing the prompt if the token has already been added. But, court.kleros.io should check if the Token is there as well, shouldn't it?
This is very annoying as you might need to close that modal 3 times or more whenever you want to use the site
