It is an S5 pro bundle with air manager and material station. I know when it does the auto leveling probe it goes over the whole plate. I can print the row in the back without an issue by itself "one at a time" but when I have a row in front it has issues with only the back row. The uniformity of the squish is what seems weird to me.
I went to take a video of the leveling and it failed. I redid a manual calibration. I started a new run and here is the auto cal video it goes over the entire plate. Had to zip the mp4 file.

I think the problem has more to do with the rear area of your print bed. The glass is tempered which results in a glass that is not perfectly flat. You get a very wide piece of glass (at least a meter) where the center is thicker and the edges are thinner. I think Ultimaker probably gets the center cuts only. But even so the glass is not equally thick everywhere and tends to be higher in the very center (like a mountain) and lower all around the 4 sides.
BUT WAIT - you have an S5? It looks like an S5 which does active leveling.
I think I know what the problem is!
Active leveling only probes in the area where the print is plus around the print a bit. I suspect there is a bug with "one at a time" where it only probes in the general area of where the first print is. Do this:
Do your "one at a time" print and watch the printer do active leveling. Make take a video. My guess is it will only probe a few points (say 16 or so) around where the FIRST print is to appear and won't bother leveling the rest of the bed.
You might be able to fix things by doing a manual level and doing a really good job of it. Maybe. But the glass might not be flat enough. If I'm right and this is a new bug I want to let the firmware people know.
