Is Auto Max HR working ?

I set up my FR245 to automatically detect maximum heart rate as explained in:

After March 20, my HR Max had the value : 161 bpm.

But since that time, I did some runs (11) with 5 runs with HR Max upper to 161. Why HR Max is not updated ? Because my age, I'm 62 and the default formula (220-age) gives 158 bpm, but the HR Max is stuck to 161.

Maximum Heart Rate
2023-03-24	106 bpm
2023-03-25	124 bpm
2023-03-28	163 bpm
2023-03-30	151 bpm
2023-04-01	151 bpm
2023-04-03	162 bpm
2023-04-04	165 bpm
2023-04-05	167 bpm
2023-04-06	129 bpm
2023-04-07	142 bpm
2023-04-11	178 bpm

The auto max worked for me. In fact I had to turn it off, because on very cold days my HR chest strap malfunction and reports a HR in the 200s (well above my normal HR), and with the auto max turned on, it would report a new HR max and then recalibrate all the zones, so suddenly my "easy" zone became difficult. I know it's not limited by the age formula, as my (real) max HR is well above what the formula predicts, and it had no problem with it. (Nor with the crazy numbers my chest strap passed out).
