Abstract not displaying in talks

[BenzoX]

Hi,
I migrated my website from the Hugo Academic template to Wowchemy. Most things went well, but now the abstract field is not displayed in talks, while it is displayed in publications, and I cannot figure out why. My "Talks" section is parameterized as follows:

- block: collection
    id: talks
    content:
      title: Selected Talks
      filters:
        folders:
          - event
          - talk
        featured_only: true
    design:
      columns: '2'
      view: compact

And the publication section is parameterized similarly.
Any ideas on how to solve this issue?
Thanks!
