### Fixed
- [#557](https://gitlab.com/coopdevs/odoo-somconnexio/-/merge_requests/557) Remove duplicate translation
This solves error when trying to overwrite the translations:
psycopg2.ProgrammingError: ON CONFLICT DO UPDATE command cannot affect row a second time
HINT: Ensure that no rows proposed for insertion within the same command have duplicate constrained values.
