Problem/Bug Chest Shop not working

Hello everybody, So I was seting up a shop for my SMP server in devolpment and the Admin chest shop won't work as I read. When I fill in all of the correct information it gives me "You Don't Have Permission To do That" Which is wierd because I have OP. Disclaimer I haven't checked if the normal chest shop is working.
I have the plugins as stated in the screenshot the console isn't spitting out anything out of the ordianry but here is it: https://pastebin.com/RHzpBP4F other info I can provide

Thanks in Adavance
