Nozle/Bed temperature settings... bug?

  1. I press pause for filament change and change it
  2. I return to work and try to change nozzle temp. When I press +/-, the nozle set temp fall to 0C degree. Printer don’t want to take any temp which I set. Next, the same situation I have with bed.
  3. I try to restart printer by switch off and on, but they have still 0 deg as setpoint. When I press “run” then they go to work with cold nozzle.
  4. I switch it off and go sleep. At morning turn on again, send to him some job and again they still show 0 as setpoint. I run it and finally he accept my new value.

Or it’s some bug or I don’t know about something.
