Add simple collision doesn't work

Hi, in UE 4.26 I’m trying to import cad files with datasmith at runtime with blueprints.
Everything is fine, but the node “add simple collisions” to static mesh with box set always returns -1.
Does someone else has experienced the same issue?
Thank you very much.

I do have the same issue, with datasmith I can’t set any collision on. In somehow fbx works better with collisions but raise other issues. If you found the work around, could you let me know please?
