When I took the cabinet from the post and loaded it up, the right stile worked fine. I never got into a loop at all. maybe if you post the steps you took to get this loop I can recreate it.
Not on Mike's cabinet. I tried with a standard framed corner and had to profile from the inside edge to get the miter on the outside edge. On top of that, the tool I used had to be upside down and backward (like crown molding ).
What I did was with this cabinet loaded up, I took the right stile to the part editor. I leave it on Front View, profile, single, then I click toward the top right hand side of the part. Click next at the bottom and select your tool, once you select the tool then specify your plunge depth and click ok. Return to the cabinet editor. Select the right end and take it to the part editor. When in the part editor change the Front View to Back View, because the CNC front of all exterior parts of a cabinet are facing inward on a cabinet. Now select profile, single, then click on the top left hand side of the part. Click next at the bottom and select your tool, once you selected the tool then specify your plunge depth and click ok. Return to the cabinet editor. Now both sides have the correct miters on them.
