How to reproduce

• Create an education.
• Unsynchronize and check one or more synchronized boolean metadata: initial education, continuing education, or apprenticeship.
• Save the education.
• Edit the education.

Actual behavior
The previously checked checkboxes aren't checked anymore.

Expected behavior
The previously checked checkboxes are still checked.

N.B: as seen in the repository workspace, the metadata seem to be valid in the repository, they're just not checked when initializing the fields in the edition screen.
