[BUG] Can't add installed datafields to Activity 15.31

This bug was reported earlier, but it's present in the Production Release too, so here is the new video demonstrating it.

Please note that EatMyRide Simple Planner isn't installed any more, but it's still displayed as available datafield still.

I'm trying to select Stryd but it selects Temeprature record instead, and if I try to select Temperature it will select Infos System...

Overall, Connect IQ fields sometimes reset to timer for no reason and swapped, there was such problem on older Fenix devices too. Sometimes you can see the whole list if clone the activity, reset it and try to add datafields there(Check screenshot below).

I already did full reset with restore from backup but it didn't help much. I may try to do a full reset again to see if this could solve some of the bugs, but I'll have to waste a lot of time setting back the watch.

Garmin-Laurie do you need any data from me before I reset the watch? 

Please also see another bugs I've reported today:
