Cannot remove subfield in the dataset form with repeating_subfields

[fabas-mpcdf]

Hi!

I am running CKAN 2.11 with ckanext-scheming 3.1.0

I have a field with repeating subfields like this:

- field_name: creators
  label: Creators
  repeating_label: Creator
  repeating_subfields:
  - field_name: name
    label: Name
  - field_name: affiliations
    label: Affiliations
    preset: multiple_text

I can create a dataset with this field but, once it is created, I cannot remove any affiliation that I add to the creator. I keep clicking on the Remove button but nothing happens (see image).

What's the problem?

Strangely, when I change ckan.locale_default from en_GB to en, it works again.
