...looking at the pic of your brass I see striations running the length of the casing and dullness around the web of casings. Do you clean your brass before resizing and if you do, what method of cleaning do you use?
... the nickel plated cases I've resized most are pistol calibers and I use carbide dies, dirty brass (even if it looks clean) will sometimes get those same type of striations in them. Minute particles of carbon on the fired casings could be accumulating and over a couple of cases could scratch the casings as well as the internal body of the dies above the carbide ring at bottom of the die. Regardless of the kind of lube used, it will act as an attractant that the scraped off carbon particles will stick to and be held in "suspension". Note: With carbide pistol dies, they "claim" one doesn't need to lube cases....yeah it will work, but it also works even easier when they are lubed, the carbide ring is just stronger and more resistant to wear. I found it takes more effort to size dirty brass, not worth the extra "convenience" of not lubing.
...You most likely already do this, but once I finish a sizing session I disassemble the my dies and clean them out thoroughly to include the seating stem & button to remove any vestiges of caked on gunk, then apply a light coat of oil with a swab, reassemble then store.
...before I switched to wet tumbling, my sizing dies for rifle cases would get an accumulation of scraped off gunk (residuals of lube, vibe cleaning media & carbon) pushed up to the top of the die above the neck portion, I'd have to stop my sizing sessions and clean it out regularly to avoid it dropping back into the die and getting scratches on the brass and hopefully none in the die body either.
...FWIW, I'd recommend you use the Hornady warranty to return the dies for replacement or reimbursement. I'd also leave that stuck case in it so they can investigate what went wrong.
