There may be some confusion about cryptomatte output, because the basic
output is different between SA and 3dsmax.
SA shows multiple colors , (similar to info passes material ID or
objectID..), but this is not the final cryptomatte output. This is not
usable by the 2d softwares as cryptomatte data.
Only the exr passes (with 00,01,02 layers) are usable and only software like Nuke, Fusion, (maybe photoshop with some plugin) are
able to use cryptomatte the correct way.
