Delmia Machining - Equipment Design

Hello Community, I am a new user of the DELMIA MACHINING APP in connection with Solidworks.
I want to create a fixture. 

Why is the component twisting? 

Why I can't create another connection? 

If I don't upload the assembly from Solidworks but import it into the platform, 
the connection works, but the part still twists. 

Watch the video.

Best regards
Torsten
