So I am new to Bambu Studio and I see there is a filament manager section. I read up on it and my understanding is that if you add a new filament to Bambu Studio and then go into Filament manager that new filament would show up in the list and could be used vs just using generic. I have tried to create a new filament one example is the Polymaker polysonic PLA plus. I went into the preview tab and clicked on gear Icon and added a custom filament. It shows up in the custom filament tab. I then click on the filament manager and that version of filament is not there. Some of the filaments I have added do show up. Anybody using this feature and can shed some light.
