Hi,
Yea that question is acting up a bit, I've had some other people have issues with it as well.
You cant assign the same number to different fliaments if you might of been trying that
Maybe try on another platform (if you did it on a phone try on a computer or vice versa)
That question can also be aswered by dragging the filaments around in the list.
Dont worry if your only filament is PLA, just aswer the rest randomly, I can fix that. Im mostly interested in looking at the top 3-4 most common filaments.
Thanks for you efforts, I really apreciate it!
