Yours appears to have done just that, its pretty flat looking.
You need to remove it from the ring, and then put a wave back in it by bending.
I use a flat bill set of tweezers to do this, and this will usually solve this problem.
But I do want to make one note. If perhaps a 6105 ring has gotten in there somehow, the 6105 ring
is thin enough to cause this sort of problem just because its so much thiner. I can not tell by the photo.
Also the wrong dial ring can cause this problem if its been monkeyed with.
Hope this helps,
