Wrong temperature in Menu "Change filament" (1 reply)

Hi everyone

I experience a problem with the "filament change" feature.
When I select (on the LCD screen) "Change filament", then the software asks for which material I would like to heat up.
The problem is, that the nozzle will heat up every time to 190°C regardles which material I select.
Otherwise, when I first select the "Pre-Heat" in the temperature menu and select for example PET, then the nozzle heats up correctly to 230°C.
Afterwards I can head over to the filament menu and select "filament change" and the temperature stays on 230°C. It doesn't cool down to 190°C like in the 1st scenario.

Therefore the selection "pre-heat" in the temperature menu works correctly but not when I go directly to "change filament".
I have attached the complete configuratioin.h and configuration_adv.h file in case this helps.

Firmware in use: Marlin-bugfix-2.0.x downloaded from github

Would be glad if anyone can help me to get this to working correctly.
