Can you handle the equivalent i18n strings also?

Does the field accept an empty value today?

For the i18n, I believe I did that correctly.

Does the field accept an empty value today?

Yes, "unspecified" is permitted in the dropdown.

Good. The i18n needs just the changes of the modified string (should be only 1-2 lines). You can exclude other updates eg pbr.

Can you please rebase!

Should be good now I think. Apologies for that.
