In my ignorance/innocence, I typed "PLA+" as the filament type, when uing Duplicate to create four custom material profiles.
Now, those profiles do appear in the Manage Materials window, but if I select one, Cura identifies it as "Not Supported", turns the "Prepare" view's Material field orange and defaults the Print Profile selection to "Not Supported". This also hides all of my custom print profiles from that printer profile pull-down select widget.
When I try to Remove those PLA+ material profiles in the Manage Materials window, the Remove button is greyed-out.
Is there a manual edit I can make to a Local or Roaming data file, or will you need to modify the software to resolve this?
PS: If indeed Cura does care what Filament Type is entered, it would be nice if Cura gave a pull down list instead of a blank field for this entry...
