You can just copy the missing strings code from the en_gb strings file to the language file of your choice and type the translation in the msgstr line and it will translate to that if your Kodi language is set to that same language in Kodi > Settings > Interface > Regional > Language.

Some of the string codes are not missing and it still doesn't work. "More like this" (in en_gb) has already been translated from "Similar" en_us to "Änhnlich" in the de_de strings file. I guess More like this and similar mean the same as they both share the same #31622, just BE and AE.

msgctxt "#31622"
msgid "Similar"
msgstr "Ähnlich"

It's still showing "More like this" though. The Kodi language and region has been set to regional > language > german. Am I missing a setting somewhere?
Thanks again

Try putting this in the de_de strings file

msgctxt "#31622"
msgid "More Like This"
msgstr "your translation"

msgctxt "#320005"
msgid "Similar"
msgstr "your translation"

And test again with Kodi language set to German.

U can explain this? I was trying the same to spanish but the 32xxxx digits msgctxt, don't works.

I can't translate all the msgctxt that begin with 32xxxx, any missing or wrong
