Stockfish 10 problem of evaluation

A position can only be drawn (0) or won (infinite), everything else is arbitrary.

I investigated a correspondence game position of mine with a minus pawn but (over-) compensation, probably won.

-Komodo & Fritz: -1
-SF9: -2
-SF10: -3

The material is „+1“ though but the engine will win the position with a high probability. What is right, what is wrong?

Default contempt values are 20 and 24 for SF9/10. Set them to 0 if this fits better in your picture of chess.
