Your leaks are under control. So you don't need to worry about that.
But your AHI is still WAY too high. The goal of PAP is to get the total AHI < 5.0 consistently night after night. Your AHI last night is almost 3 times too high and the longer term AHI's are also way too high. On a diagnostic sleep test, an AHI = 14.98 = 15.0, would land you with a diagnosis of mild-to-moderate OSA.
Moreover, the thing that is making your AHI way too high is your Obstructive Apnea Index (OAI). Your OAI is still WAY too high at 12.44 (last night) and 8.80 for the whole time you've used the machine. This indicates that your airway is still completely collapsing way too often. And it probably means that the current pressure setting is not quite high enough to properly manage your obstructive sleep apnea.
Last night's AHI may be higher than the previous nights simply because you did sleep all night with the mask. REM sleep tends to increase as the night goes on, and so it's not uncommon to have more events in the second half of the night. Of course, if you were sleeping without the mask for the second half of the night, your real AHI would reflect the 30+ AHI on the diagnostic sleep study.
What to do: I'd report this problem to the sleep doc if I were you. I think you are still way too new to PAP to be messing around with your therapy settings all on your own. But the sleep doc needs to know that the total AHI reported by your machine is still very high. My guess is that the sleep doc will either authorize a (slight) increase in pressure or perhaps a switch from straight CPAP to an APAP with a pressure range.
