Does it look like the bottom blade is actually causing a wear pattern on the blade beneath it? That would be a good indicator of something being wrong.
That's precicely what it looks like, and the one with the tip down certainly isn't the bottom one. But it seems to work although it feels wierd to buy such a lens.

Thanks,
