Filament loading error messages - but not experiencing any filament loading problems

Thought I'd see if anyone is having similar problems, before I refer to Prusa Support.

Have a Mk4S with MMU3.

Recent multicolour prints are displaying the following message after completion of the print.

"Printer has detected multiple consecutive filament loading errors. We recommend checking Nextruder main-plate. Visit prusa.io/mmu-care"

I am not experiencing any loading or unloading issues. (Perhaps unloading might be a little slower than normal, but not 100% sure if this is actually the case or normal operation.)

The printer keeps a running tab of the number of MMU loading errors.  Once that number surpasses a certain threshold you start seeing those warning messages.  You can reset the total back to zero from the printer menu; I think it is in settings.

MK4S/MMU3
