Sorry for the long time without updates. Im very busy recently with my own minecraft server. But now there is a update for you!

Added support for PowerRanks in the shop ( https://www.spigotmc.org/resources/powerranks.64696/ ) now you can use PowerRanks plugin and when player buys a kit in the shop KP-PVP will make the console execute PowerRanks command to give player permission to the kit
Now you can disable Switcher kit in kits.yml (Some people are complaining it caused issues with Citizens NPC)
Fixed bugs in Gladiator Kit (Like the glass arena doenst disappear after the battle sometimes)
Now you cant use ender pearls in Gladiator (It fix people with Jumper kit being able to use ender pearls and escaping the gladiator)

I recommend you deleting your kits.yml and configure it again

Thanks for your support. If you encounter any bugs report it to me
