Heatermeter wonky

[MartinB]

In the middle of a cook I went outside to Spritz and found my heater meter looking like this......
Still working fine via Wi-Fi on my phone.......but showing some garbage reading in huge letters on the display.
When set to large Probe 1 reading.....but probe 1 is 260F.......not this

Is there a probe that has that temperature? I just tested with my HeaterMeters and they all display the right value when the Large Home LCD mode is set to that probe. I've even tried enabling lid mode and it seems to stay working fine.
