Steps to reproduce:
Liferay 6.2 SP17 + Social Office 3.1.1 deployed.
1. Add Test test to the users of Social Office (Control Panel/Social Office Configuration)
2. Then go to Contacts Center.
3. In My Account/Display Settings, change the default language of the user to French and refresh the page.
Result: In the list on the right side, one line is still in English: "You have 0 followers."
The translations were added by the Story
LPS-64252 to master/DXP, which however cannot be packported to 6.2.
Thus, I opened separate ticket to add this specific translation to the Contacts Center portlet.
