Thank you for your contribution to Keyman! We will make sure it is included in the next major release of Keyman. We are working on making the localization for Keyman more streamlined in version 12, and at that point will establish processes to make it easy to contribute, edit and update localization files.
I’ve logged this for investigation in the 11.0 timeline. If the fix is straightforward we may be able to push it into a 10.0 maintenance update as well.
