Randomly Dropping CIQ data fields

For the last month or so I have been having lots of difficulty with my CIQ data fields, which I use on almost all of my activities (Walking, Running, Cycling).  

After years of using these on previous devices, and a year+ on my 965, they have become extremely unstable and often get replaced with the "IQ?" symbol - usually fixed by me editing the datafields, deleting the CIQ field(s) and then readding them back.

Worse, on my run this morning, my Stryd Zones datafield was simply dropped altogether - which I didn't realize until I was almost halfway done with my run.  Those with Stryd know, that means I didn't get any of the power-related metrics for the entirety of that stretch.

This is similar to lots of odd behavior from my watch, reordering glances/widgets on its own, etc.

Anyone else experiencing this and/or know what I might be doing wrong?
