xDesgin - STEP / IGES Import - Error

Hello,

i have some Problems with Step / IGES import...

 

Import File in xDesign:

Then i save the File, close it and open again:

 

WHY???

Before the update it worked perfectly. 

 

I tried it with a .step and a .iges file, both times the same

 

Does anyone have an idea why this is

Thanks
