It looks like a manufacturer's defect to me. Looks like injection molding gone slightly wrong - maybe a bubble or a mold not quite filled up. I worked in a place that made plant pots and sometimes they came out of the machine with gaps in the rims, and I had to stack the good ones and toss the bad ones into a bin for the grinder. Looks like they skipped that bit.

Fright Night (the 1985 one). I was 6. The idiot daughter of the woman babysitting me thought I was asleep on the couch, so she put it on.
I was not asleep.
If they're injection molded, and there's a problem with the flow or the pressure, it could produce several runs that have the same void in one pan before someone notices and fixes it.
