The first thing I notice is the high leak rate, probably from your mask, or possible mouth breathing.
If you look at the leak rate graph, it correlates with the Obstructives on graph.
The thing is, when you experience leaks, the APAP will try to compensate and shoot the pressure up. It's hard to say if the AHI is accurate at that point.
The first thing to do is determine if you are mouth breathing, and mabye use a chin strap.
Make sure you are using the correct size nasal pillow. Try one size up.
Other than that, you can move your minimum pressure to 9, as that would help clear up Obstructives. I would leave the max pressure alone right now, unless you see on the graph that it is staying at max for a good part of time.

It's barely legible.
Does look like big time leaks in the time frame of that clump of scored apneas.
Machine results cannot be trusted when leak rate is high. You need to tame those leaks.
Looks like you can get a seal at that pressure later in the night.
You may need the next size up pillow for the P10 mask.

Don't dwell on it too much, blame it on your congested nose. Try saline sinus rinse an hour or two before bedtime
Full face mask is your best friend on those occasions
Edit: some people get congested on higher humidity settings, some on lower settings, and some happy without
Matter of trial and error, might get lucky to find the sweet spot
Avoid sleeping on your back helps, try the tennis ball trick or something else prevent from rolling on your back
zoom in on that area and see how the leak spikes relate to the OA's

I don't think, leak is the main problem, only after the fact
When your nose is congested and using nasal mask, no sufficient air passing through
You'll have to open your mouth to get some air to breathe, that results in mouth leaks
Hence the large leak during this time and none at other times
Thanks to all for the ideas. I suspect it was a mouth-opening problem, I did have a looser chinstrap than usual.
