Grooms are not showing up in object ID pass, but they are okay in any other render pass.

I have set up my scene to render and composite in nuke, everything is alright, but, when I render the object ID pass ( Cryptomatte ), the groom is not considered in it at all.
I have other projects with groom that it works perfectly, but I don’t know what is the reason it’s happening here. I tried bringing the grooms to the scene separately, attaching to an empty actor to have it like an skeletal mesh, none of them worked.
