I'm not quite as sure TBH, I do agree it's something that was there that now is gone, but to my untrained eye it looks almost as if it/they were ripped from the stays and JB weld gooped in the resultant holes.
Looking closer, it does seem possible there are in fact no holes but only way to know would be to carefully dig out the filler. If it were me, I'd probably return it unless it's something super rare you're not likely to find/afford again.
Then again, if it IS structural they'd only pass it off on someone else so I'd be tempted to go down
@klunkrider 's suggestion of carefully filing down & if any holes appear then go from there (scrap it or have repaired).
You said you didn't want a huge debate on it, and here's me giving you my internal dialogue's own rambling crap lol sorry.
