Go to the link of whatever club you wish to leave. I don't know which one you want to leave, so I'll provide the links for every club you're in:
Warzone: https://forums.minehut.com/clubs/23-warzone/
Juice WRLD: https://forums.minehut.com/clubs/56-juice-wrld/
Skript: https://forums.minehut.com/clubs/206-skript/
Minehut Events: https://forums.minehut.com/clubs/55-minehut-events/
Once you're on the club's page, look to the bottom right of their banner for the Leave Club button. I'll use the Warzone Club as an example of what this looks like.
Hit Leave Club, then Ok, and you should be good to go!
I noticed you're not in a club you own, so my apologies for the unneeded ping if you needed to delete a club you owned and you've already finished this, however for future reference, there's really no need to delete a club you own merely because you've changed your server's type. You can simply just renevate it to fit the server you're attempting to create under Manage Club > Club Settings, which is found in the same area as you'd find Leave Club on a club you don't own. Just make sure you're on your club's link.
