HUD position spontaneously reset

[raincitysun]

I got into my 2018 Mazda3 GT the other day and the position on my HUD display was missing. I checked the settings and it was about halfway up--where I had set it--but the display was way off the top of the HUD panel. I've been able to adjust it so I can see it again, but now it's just one click off the bottom.

Is there any known issue with HUD positioning changing? Any way to fix it?
