Description
Fixes typing: Important this is not a translation change, this is an internal change of the value field for the translations - another important thing to mention: This (probably) has to be changed in all language translation files as well and also in the general value context if it's wrong there as well and copied

Same thing here - will need to update where in the codebase this is called from (I think a fragment). All the translated files will automatically update so nothing further for you to do on that specific avenue.
