Empty actor when importing from SOLIDWORKS or STEP, UE 4.19.2

Hi, I have an issue here… I managed one time to import an assembly from SOLIDWORKS into UE 4.19.2, but most of the time I get an empty actor with no meshes inside. I did get more success with 2017 files then 2018 files though (SOLIDWORKS has version specific files). I’m I importing the files the wrong way ? the image attached to the post show my import settings, they are the defaults exept I removed Lights and Cameras

I also tried STEP 214 files, it works but the UV maps are all messed up. Is there a way to fix UV maps after importation ?
