Not sure what OS you are on or what printer But the few I have done i just copy the supplied json files into the appropriate user directory (windows is like /user/appdata/roaming/Bambu/… I don’t have that machine up so can’t check) there are posted links in other threads on here. I don’t use /default/… but the numbered one.
Also, seems like some one else was posting about eSun and their issue was that it wasn’t listed under eSun, but something like Basic or PLA was the first word in the listing.
Sorry for the ambiguous info.
Also the filament name does not show up on the device/AMS page as far as I recall (don’t have access to a slicer at the moment), it will say Generic PLA or something. The filament name does show up in the drop down on the prep page in the drop down where you add or subtract for multiple spools, or select nozzle.
