After reboot erratic fridge temp setting

I’ve noticed on a couple occasions that after a reboot that all of a sudden (while running the same beer profile) that the fridge set point jumps for a bit before correcting itself. The result is that the heater kicks on even though the beer and fridge at actually right at the “right” temperature. Has anyone else encountered anything like this?

For example:

beer set point: 59F
beer temp: 59F
fridge set point: 61F
fridge temp: 61F

then after reboot for about 10 min:

beer set point: 59F
beer temp: 59F
fridge set point: 77F
fridge temp: 61F
heating is called for and starts running until fridge set point eventually starts dropping to previous setting of 61F.

Here is a screen grab from the most recent example of this:
