You are being shield from demtoion

So I had this you have been shield from demotion thing on my profile overview at first. Won a bunch of games looked back and then noticed its gone. I then go to the ranked tab just to see where i was at and then i saw the warning message for shielding from demotion again, and if i click my overview it will show the warning message there as well. But if i go back to home and click profile the warning message is gone from the page again. Not sure if bug or intended. But yeah just letting you know that is weird =/
