For some reason, the Crashlanded.label & Crashlanded.description never used the translated string, in any language I tried... They seems to always used the english version.

Not a bug.
This is a problem with the translations themselves not translating that part of the game which is why they are displayed in the default English language.
The translators need to translate the \DefInjected\ScenarioDef\Scenarios_Classic.xml and \DefInjected\ScenarioDef\Scenarios_Special.xml files.
