It used to be that all my filament profiles were in alphabetic order in the dropdow list - user filament profiles in the first section sorted alphabetically then system presets in another section, also alphabetic.
Some time ago after one of the BS updates, this changed and they seem to be completely random. When you have dozens of filament profiles it’s very hard to fine the one you want to assign to the filament slot you are using in the Prepare tab.
Without knowing how it’s organized, it is random and chaos in the real world.
Maybe it’s based on the binary spelling on the middle letter spreading out left and right. Or, it’s based on the number of socks my dryer eats while printing a certain filament brand.
