Checkmate in Antichess Shown on Computer Analysis?!

Request a computer analysis of that game. It is an Antichess game. After the first move it showed "Checkmate is unavoidable." And then it reapeats again and again as the game continues. What on earth is going on? Checkmate is not a thing in Antichess! And it was shown after only the first move! How ridiculous. This should be fixed.

checkmate here refer to win and in antichess the move e4 will give a mate in 15 moves for black. engine is perfect here.
