Unwanted default clef inserted on new MEI file

What you were doing

When I use Neon and create a brand new MEI file, it seems that an "invisible" default clef gets added on line 3. When I export this, I can see it in the output MEI, and also when I upload it in a different viewer i.e. Verovio

Unsure if this is a user issue from me or a bug. My expectation is this should not happen.

A workaround is to just edit the MEI file directly and remove the clef, which is not too much of a big deal.

What you were using

Attached output MEI file and source image. Unfortunately GitHub does not allow MEI or XML, so uploaded as TXT. 0286_Plut._29.01_Carta 139v.txt 0286_Plut _29 01_Carta 139v

staffDef defines the default clef information when there is no clef found on a staff. It should not create a clef. Is this still happening for you?

Also, the MEI files exported by Neon cannot be directly rendered in Verovio. For more details, please check this page
