Titles carry over from server to world

I was playing Cakewars on Mineplex with some friends, we were all in one party, and I died. When the count down to respawn started, I opened the pause screen. I kept the pause screen open after I respawned, a couple seconds after I respawned, I selected Save & Quit. Once I successfully left Mineplex, I joined one of my own worlds, when the world loaded, the actionbar title that Mineplex used in Cakewars appeared, then faded out shortly after, when I opened the pause screen, it showed my gamer tag, and both my friends' also.

 

Sincerely,
