How do I import STEP files into SW?

Hi all

I have problems with components that get mistaken and disappear when I import WWTP on SW of complex assemblies. Especially when I click on "Break function" in order to be able to save some sub-assemblies.

Is it coming from my settings? 

How do you import/register your WWTP that is sent to you?

 

Thank you for your help.
