Please find attached 2 sample files. 1 from SS4 and 1 from 13.1. For some reason step file import doesn't work properly in U13 compared to SS4. Can that be looked at?
SR raised 7000978107
Working on your issue to see what might be the cause of this discrepancy between the two versions.

I will link your SR # 7000978107 to this Defect.
Thanks Andrew. Does that mean U12 is the version to go back to if I want to work with step files?
