AMS Auto-Refill change breaks usability

In the chart above it goes.

  • A1
  • A4
  • B2

If A1 is used and runs out during the print, it would go to A4.

The empty spool in A1 could then be replaced with a new spool.

I am unsure if the AMS will acknowledge the new spool as I am unaware if adding a new spool overrides the knowledge that it was empty before. It has all the sensors, it could, I just do not know if it will.

However, there are two issues:

  1. Three different colours are shown, this should not show different colours based on the rules of Auto Refill.
  2. Filament Backup is disabled, it should show ANY option!
