Case for Digione signature + USB Bridge Signature

[ale76]

I could easily mount the Digione Signature and it works like a charm, however I am facing some issues with the case. 

THe "Clean Power" plug on the case is at the same height of the DIgione card, and it prevents the case from sealing. 

Same issues for the "clean power" connector, which is at the same height of the Ground screw.

 

Seems like the Digione should be lifted by 3/5 millimeters. 

I tried all the different screws and spacers, but no one seems to do the job, because they lift the Digione too much.

 

Any suggestion ? Maybe I have a defective case?
