I Didn't Get to Select A Promotion Piece; Why Not?

My game ID is Game 12260588

When I captured my opponent's Rook and at the same time reached the 8th rank, the game did not let me choose what piece I wanted to promote to. It automatically changed my pawn to a Queen. Why did it do that? What if I had a stalemate because it automatically chose a Queen? This is a programming change that needs to be made.

Help Please,

When a pawn is in a promotable position, you can choose the promoted piece below the "Submit Move" button.

You can experiment with this right now, in any game make an illegal move and move a pawn to a promotable rank. The promotion options will appear.

Promotion to a queen is the default, unless you specify different. Before clicking the 'submit move' tab, choose your promotion piece- then submit your move.
