Point Load at Bottom of Door Jambs

[Structintern3]

Hey guys,

So I do work on the Simpson CFS designer program and one thing I've noticed is if I do a door opening where the opening is directly on the slab, I still get a point load on the jambs at the bottom from 4 way loading. This is just incorrect right? I don't see any reason a point load would be going to the jambs at the very bottom(where the slab is located).

Please let me know if I'm misunderstanding something here.

Thank you!
