How to reproduce

I have sliced existing project that worked. Just wanted to duplicate items to print more at once.
It is a PLA + TPU print, in the previous version it would set bed temp to 60 degrees.
In the printer file selection preview screen, it reports bed temp 60 for the print but when prints it starts with the cold bed

I have switched on the original printer profile, no difference

Actual results

I have changed the printer started GCode to dump values.

; --- initial_extruder: [initial_extruder]
; --- has_wipe_tower: [has_wipe_tower]
; --- total_toolchanges: [total_toolchanges]
; --- T0: {is_extruder_used[0]}
; --- T1: {is_extruder_used[1]}
; --- bed temp initial extruder {first_layer_bed_temperature[initial_extruder]}
; --- bed temp extruder 0 {first_layer_bed_temperature[0]}
; --- bed temp extruder 1 {first_layer_bed_temperature[1]}

The result comes out as following:

; --- initial_extruder: 0         
; --- has_wipe_tower: 1          
 ; --- total_toolchanges: 91      
 ; --- T0: true                   
 ; --- T1: true                    
; --- initial extruder 0          
; --- bed temp initial extruder 0 
; --- bed temp extruder 0 0      
 ; --- bed temp extruder 1 0

Expected results

Bed temp for extruder 0 should be 60 and for extruder 1 should be 40

for me it woks fine SM J1S

; --- initial_extruder: 1
; --- has_wipe_tower: 1
; --- total_toolchanges: 5
; --- T0: true
; --- T1: true
; --- bed temp initial extruder 59
; --- bed temp extruder 0 60
; --- bed temp extruder 1 59

You chose the wrong print bed. There are no bed temperatures stored for this filament for this bed type, which is why 0 is being output.
