It seems to be a common misconception that the order or numbering of filaments in the studio pallet has something to do with AMS slots - it doesn’t even when you load the pallet by synchronising with the AMS(s).
When you start a print studio tries to match used studio pallet filaments to AMS(s) slots by type and color. I don’t know which it chooses when there is more than one match (probably the first one).
