How do I unlock trampolines gambit. The explanation says "Land a piece 5 times in one game"

I have done this numerous times and the counter never goes up even checking after each piece is landed. I've seen it go up seemingly at random, however I've never got to 5, 3 being my highest. Just went to one game and landed 5 pawns over 5 turns within one game and it did not even go above zero.

Please hello understand, this is the last gambit I need to unlock.
