Best: in Bambu Studio, select the printer, get its filament list right (sync it, or set it by hand), choose File > Save Project As, then load that file here. Plates for that printer then open in Bambu Studio on that printer, with those exact filaments in that order.
Or list the filaments yourself, in the same order as Bambu Studio's Project Filaments list (1, 2, 3, 4…). Those plates keep whatever printer and filaments are open in Bambu Studio. Either way, student colours are matched to the nearest filament.
