Weird Server Error

when my spacebuild2 server starts it shows this really weird error: Warning: Player issued command but is now vanished <Command was “p 64”> and Warning: Player issued command but is now vanished <Command was “r 64”> i have no idea what they are and i am wondering if they are bad or just random glitches

reinstall spacebuild, if that fails your doing something wrong k!

never minde i fixed it the gamemode was setting something wrong
