trane showing low battery?? What battery?

Vera2 UI2 1.0.994 (yeah as soon as I get a weekend there I plan on upgrading)
Trane thermostat.

Logged in remotely (haven’t looked at it in about a week) and saw this low battery warning on
the screen (image attached). I double checked the trane on my home setup (UI4) and my trane
at home… no battery in it. UI4 doesnt show battery in advanced area. UI2 does. Is this something
I can just ignore since it obviously has no battery in it.

Was looking at it again today… got the bright idea to clear the data from the battery field and save it.
Dashboard now shows no battery like it should. You tell me…
