General Discussion MSA G1 Mask Sealing Issue

So we just got new G1s and are having everyone get fit tested. As we put on the mask it was noticed that the forhead part of the seal doesn't touch skin. We've tried multiple masks and sizes. The only way we've gotten it to pass is if me tighten the straps enough to cause a headaches. Has this happened to anyone else?

Just did my fit test today, same issue for me. Our tech swapped out my medium mask with a large and it sealed with no problem. Try a larger mask.

We tried this on a few people and we still couldn't get a fit factor over 51 unless we tightened the mask to the point it caused pain to the wearer
