Something Unusual Happened With The Syntax Correcter

I have attached a screenshot of what happened. It is basically: I was coding away and when i reached a While loop, the syntax correction suggester said that it was missing a colon at the end of the line when there is clearly already one there. Please help

fyi: it is a colon that i put in not a semi-colon

Edit: It is an If statement, not a while loop. Although, the same happened when i put [ while 1 = 1: ]
