Hello Josh,
This is normal. I suggest:
1) raise the cap a little bit higher, your eye brow is sitting a bit low for an ANH-Stunt. When you blot the cap to the face plate the plastic will spring and it might drop a bit further. I think leaving a 5-10mm space there might be better.
2) re-evaluate the gaps on both side after you raised the cap. You might find the left ear gap closed (or very close to no gap). As long as the disc (top) of the ears have sufficient overlapping (cap overlapping faceplate area) you will be able to secure the ears without problem. IF there is a gap at the bottom edge, my solution is use a large piece of scrap plastic, bend it to shape with a dryer, then drill a hole in the middle and use it to "sandwich" the lower edge of the cap and faceplate from the inside with the bottom ear screw, with a bit of E-6000 to secure it in place.
Hope I am making sense.
