FW update bug: "model was sliced for another printer model"

After updating my MK3S and MMU2S (with MK3S_MK3S+_FW_3.14.1_MULTILANG.hex and respective MMU2S_MMU3_FW3.0.3+896.hex), my printer displays this error message "model was sliced for another printer model" every time I try to print a model (sliced correctly using PrusaSlicer 2.9.0).

I verified the gcode in subject and it contains the correct printer model check: "M862.3 P "MK3SMMU2S"

So, the only logical issue remaining is that the printer is now looking to find a different string at the printer model check in the gcode.

Finally, the questions I have are:

1. What is the updated printer firmware looking for to find in the gcode when it does the printer model check?

2. How do I properly fix this issue? (hopefully without removing the printer model check from the original printer start gcode)

3. Does Prusa have any plans to fix this bug?

I am also having this issue since installing 3.14.x - I have not changed anything on my slicer only updated the firmware to the printer.

Any thoughts @Pruse3d?

Same here.  "G-Code Sliced for a different printer".

Same!

I only updated to get rid of the version number warning, now i get "model was sliced for another printer model" before every print

GCODE has 
M862.3 P "MK3SMMU2S" ; printer model check

Printer lists MK3s as the printer and MMU active

Print works normally after accepting the message

I print via octoprint, so having to go click ok on the printer is very annoying!
