Far Sector 1 2nd Print 9.6 - Damage post grading or something else? 1 1

[SWorsdale]

Sent a few comics to cgc in march ago and received them shortly after. When going through them today i noticed this damage on the comics.

Still very much a newbie with grading, unsure if something in the slab but appears to be on the comic?

The color rub could be from mishandling, but not sure what's sus about the edge.
