PulseOx Turning itself on to all day by itself

I noticed that happens since 17.72 Beta ... but only once after installing the actual update. Once switched off it keeps ... until next version. 

I noticed it does like every other day because I can see the red light on the back of the watch turned on.

Did you switch it of manally?

I changed it manually from all day to during sleep.  The problem is I checked the next day and says all day again and have to change again back to during sleep.  I noticed because the battery was being drained as the pulseox all day is a battery killer.

Strange ... mine seems to keep the settings.

It happened again this morning.

Same thing this morning.  I think it is a problem with the battery saver changing it's setting.  I have it set to pulse oximeter don't change but it is changing it to all day for some reason.

This is annoying, every time you start or finish an activity it switches to all day and I have to go check and turn it to during sleep.  I think it has to do with me turning sensors on/off for the activity (stryd, tempe and polar hr).
