Ams2pro ams auto-refill

Couple of questions

1- If you have more than one AMS, and ht and you have AMS AUTO-REFILL check will it pull the refill from another ams as long as it is the same type ie pla, generic, black ect?

2-I understand that you need to do this prior to sending the print to the printer, I refreshed the filaments in the slicer, sliced it then sent it to the printer. It told me that it was going to draw out of ams-b slot 4 which was the one that was going to run out. I placed the refill in the ams-ht and verified it visually just prior to after slicing and hitting the print button, but it failed to do it?

What am i doing wrong?

Both filaments were set up on the h2c and refreshed in slicer as GENERIC, PLA BLACK

Thanks

This includes the printer settings also (not tried with seperate ams units)
