Form results are incorrectly shown if user language is set to a non-default language

Steps to reproduce:

1. Start the portal and log in as Admin
2. Go to Content > Forms and create a new form
3. Add a Multiple selection field (Eg: 1,2,3)
4. Add this form to a page using the Form portlet
5. Submit the form (Eg: select 1,2 and submit)
6. Go back to Content > Forms
7. View the entries for the form
8. In the overview, see that the selections are properly listed (1,2)
9. Go to the detail of this completion (Ellipsis menu > View) and see that the checkboxes are selected (1,2)
10. Go to the Account Settings of the user and switch the language to something other than English (eg: Hungarian)
11. Go back to Content > Forms
12. In the overview, see that no selections are listed
13. Go to the detail of this completion (View)

Actual behavior: The checkboxes are not selected. Refresh the page and see that the boxes are initially selected but the checks disappear.
Expected behavior: The checkboxes are selected.
