Translating courseHomeMetadata.factory.js

Hi,
I reviewed and translated much of the strings to fr_CA, and there are still strings that are displaying in English. 

In particular, I found that the titles from 
https://github.com/openedx/frontend-app-learning/blob/master/src/course-home/data/__factories__/courseHomeMetadata.factory.js

are not translated/translatable. 

How can we do this ?
