[Risolto] Translated Strings are not showing up

Background of the issue:
We are translating the site link nascosto into Spanish and Japanese. Both languages are not showing to the public yet until translation is complete. We are using the 'display hidden languages' in the User settings to show the progress. So far all the pages are translating perfectly.

Symptoms:
The Mega Menus at the top are not translating. The actual strings associated with these Mega Menus have been translated, but the translations don’t show up.

Questions:
Can you please provide some guidance?
