Display showing wrong temperature setpoint after filament load

[Hanier]

Printer: MK4
FW: 6.0.0

Steps to reproduce:

Unload Filament - PETG in this case
Reset Button - Go to known state
Allow nozzle to cool below 150C - Arbitrary chosen value

Push-Load Filament into Nextruder
Select PETG when asked
Waiting for nozzle to reach setpoint = 230C

Purge OK - Select Yes

With no additional user interaction

Display goes to main screen
Lower-Left shows nozzle temperature dropping
Setpoint Shows 230C
Temperature stabilizes at 170C
So... Lower-Left now shows 170C/230C

The nozzle currently remains heated at auto bed leveling temperature after load/change/unload while showing the final temperature. It's intended behaviour, but I don't think it should be (see comments on the issues).
