The T60 nets for the Lc0 engines are making various errors- so, if you are using it for endgame analysis I would switch to either the sv t40 1541 net or just use the latest SF dev.
It seems when there are many options to win the game Leela doesn’t feel the need to find the best move and can throw away the win. Stockfish, being a brute force engine, just finds the quickest win.
