@Alternon Hello,
By "deleted the Source line" you mean you removed the metadata sub-element "Source" from the "Description" metadata element?
For what I can tell, "Description" is composed of two sub-elements: "Text" and "Source". When entering values, it doesn't matter if "Source" is empty or filled: in Pawtucket the semicolon will always appear following the description; if a "Source" is provided, there won't be a space between the semicolon and the data provided in the "Source" sub-element field. That semicolon is certainly annoying.
The metadata element .description has a setting named "Value delimiter" set to ;. I had expected this would separate multiple ca_objects.description entries in Pawtucket, but changing it to - or , will make no changes.
