Question Help, I used /v now its glitched....

Hey guys, I used my essentials /v command to spy on some players, and now, even though I disabled it, I appear invisible and offline to random players, some players can see me, some cant. Now I have to do /v twice to turn it on and off to become visible again. I cant find anything on line to fix this so It would be great if someone on here knew how to fix this issue.
