It is not surprising because it is a null move problem.

If black has the right not to play then white cannot threat the black king at
d7(the pawns cannot move and the bishop cannot see d7)


I suggest that you use better programs like Genius3 for analyzing studies.

Junior is also better in this position but it has practical problems in other
studies
(for example when there is under promotion)
