@adamstankiewicz looks like Frontend App Gradbook didn't have the required variable in LANGUAGE_PREFERENCE_COOKIE_NAME='openedx-language-preference' and the translations didn't work.

[adamstankiewicz]

LGTM! Good catch on the LANGUAGE_PREFERENCE_COOKIE_NAME. FWIW (as a sanity check), for 2U/edX deployments of this MFE, the missing LANGUAGE_PREFERENCE_COOKIE_NAME was a non-issue in stage/production as our internal configuration sets this setting as a common environment variable applicable to all MFEs.

Definitely should be there for local dev though!
