GFCI Breaker

[rbeach29]

Installed a 2 pole 30 AMP GFCI breaker. This supplies one dedicated 20 amp breaker for an espresso machine. It is wired with 10/3 mx cable. The beaker trips immediately if the outlet is in the box. If the outlet is not in contact with the box, via the screws, the breaker stays on and does not trip. Once the outlet makes contact with the box, it trips. As far as I can tell, there is no ground/ neutral issue, and no short can be found. What might be causing the breaker to trip?
