Remove trailing comma in affiliations

[jgilis]

Hi,

I just noticed that with multiple affiliations, a trailing comma appears.

For instance, if I do:

author: 
  - name: Author1
    affiliations:
      - name: Ghent University
        city: Ghent
  - name: Author2
    affiliations:
      - name: Padova University
        city: Padova

I get the following:

If possible, could the trailing comma on the last line be removed?

Ran into the same issue. It appears all attribution elements except postal code are followed by a comma, regardless of whether there are subsequent elements. For now, I'm forced to put in the full address of my institution so as to not have an awkward comma at the end of the name.
