Game review shows a draw?

Towards the end of my bullet game (move 79), game analysis saw a position where I was up queen+king vs king as a draw. When I see the line it suggests, it says I am winning. I am curious to know the explanation for this and if it is some sort of glitch.

Opponent could claim draw by 3-fold repetition of the position with 80 Kg8.
The same position on moves 68, 78, and 80.

But how? If my opponent would go Kg8, I would go Qc7 and eventually checkmate.

idk

Your opponent records 80 Kg8 on his scoresheet, claims a draw by threefold repetition of the position and stops the clock.

Ohh, I see. I'm 1700 and I just learned the rules of threefold repetition, wow. Thank you @tygxc
