Help with PSA/DNA Authenticity Ghostbuster cast signed photo

[Kenny Brian Regiec II]

Hello I'm newbie here. I'd like to get others opinions on this item I purchased on eBay recently .Its a Ghostbusters Cast signed 8x10 with 4 autos:Bill Murray,Dan Aykroyd,Harold Ramis, and Ernie Hudson. I never normally buy autographs through eBay or over internet. But I've been wanting a cast signed Ghostbusters photo/poster for a long time and finally I came across one that came with PSA/DNA LOA. So I jumped on it. The item came from France (seller was a fan/collector). The photo/signatures look great and the cert number matches up with one on the PSA/DNA website Cert# AA01416 . The Letter Of Authenticity has the proper watermarks (DNA chain, and logo) as well as the holographic logo that's part of the LOA's paper itself. Everything matches up great . I just have one little minor concern. The PSA/DNA tamper evident sticker on the bottom right of the photo itself has some really small minor little cut or marks on it. Almost as if someone maybe once tried to lift small part of it off and stopped. Looking very closely when u hold it up to the light you can kinda see two little glossy areas almost checkering is best way I can explain it. I understand the stickers are supposed to checker and break apart from what I've read but can't find any pics online as to what it actually looks like so I can compare mine. It almost looks like the sticker has a glossy coating on top that is what's starting to checker a bit. I've emailed PSA 3 times and haven't heard back. I'd like to avoid having to send it back to them to verify but if that's what it takes I will. Again everything seems good the item matches on the website and it's def not a copy because the ink on the autos have a different glare when held up to the light . Just those little markings one the sticker have me little concerned and I want to rest easy knowing for sure I didn't get ripped off. Somebody could have possibly just tried to remove it because they didn't want it on there and stopped . I just don't know nor do I have a lot of experience with PSA/DNA . Will post some pics of the sticker as well as everything else if anyone has any tips or recommendations I would be very greatful! Thanks so much !

It looks fine to me, the PSA cert is definitely real and Steve Grad signed the letter. The markings on the sticker could be from anything, if I had to guess I would say it got a little scraped up sliding the photo in and out of a top loader.
