Fieldset using 2 of the same partials only shows one

So, I have this:

title: Test
taxonomies:
  tags: true
create_title: Test
fields:
  ctaOne:
    type: partial
    display: 'CTA One'
    fieldset: cta
  ctaTwo:
    type: partial
    display: 'CTA Two'
    fieldset: cta

But when adding a new entry of this type, only one of the cta partials is shown for me to add data for.

Is there a workaround for this?
