Multilingual support for sensitivity labels in Office Web

Hi All, 

Does anyone have experience with deploying multilingual sensitivity labels within tenants?

We have deployed OOTB English default sensitivity labels for a client that would like to deploy them for MUIs globally at some point. During testing for implementing add on languages, the MUI worked for both French and German MUI users in Outlook Web and App, but not for Office Web (see below images). The deployment was through the Security & Compliance PowerShell EXO V2 Module. It also looks like this may be the reality of the MUI at the moment - https://feedbackportal.microsoft.com/feedback/idea/196dbd7c-0343-ec11-a81a-0022484e21f1. Suggestions would be most welcome. Thanks!
