Prestige master ?

So i hit level 55 prestige 10 and am a prestigious master. Currently level 61. But after every game it says congrats your a prestige master and can level up to lvl 1000 without losing anything. Then I hit continue and it shows me this ? What is this lol. I just keep hitting not right now cause I'm confused.
