First off, this is a thin crust. Dough comes to the store pre-made with perforations, you might get one small bubble in a thousand pizzas. So, not a bubble issue. (sorry @Ghyste@sh.itjust.works)

2nd, the pizza was cut previously from the incident as indicated by the cut marks of the classic "8 slice-large". These cuts have been covered where the cheese has been squashed from the smushing After cutting. (sorry @anothercatgirl@lemmy.blahaj.zone) Also, the ovens are designed to only allow a particular height through, bottles on top of a pizza wouldn't even make it in and the smell would be atrocious.

C, the standard thin crust from PJ's comes only with special seasoning (a small paper packet of seasoning) and some pepperoncini peppers, it does not contain the round garlic sauce containers. If it had, the marks would start round and end round. (sorry again @Ghyste@sh.itjust.works)

Two likely culprits in my book, one would be the oven attendants personal bottle. On busy days you have seconds to cut, package, and add all the sides (wings are the worse with extra sauce on them and extra side sauce you always run out of). Damaging a pizza can be a daily occurrence. Lastly, probably a sauce bottle itself. There are several of such size and design for the garlic Parmesan, buffalo, bbq, etc. Whole container full of bottles you usually hand off to someone helping you catch up and probably dropped it into the open box after cutting and before putting on the heating rack.

The reality, this was probably a bad pizza set off to the side on the heat rack. There are no sides present and typically you'll see a wet residue from the peppers once they're placed in the box (you don't put sides in a bad pizza/one being remade). The slice stolen was probably a co-worker grabbing a slice during working hours and another co-worker took the rest home. Probably thought it was funny and snapped a photo for the sharing feels.

edit: changed cooling rack to heating rack, I will now perform Seppuku with my pizza cutter for my disgrace.
