ES Mobile with Language Override

Hello!

I have a language override for:

COM_EASYSOCIAL_GROUPS_CLOSED_GROUP_INFO_DESC="You need to join the group first before you are allowed to view the contents of the group."

to say it more clearly:

COM_EASYSOCIAL_GROUPS_CLOSED_GROUP_INFO_DESC="You need to be a member or logged in to view the contents of this group. Please request to join the group or login first."

This seems to work on the desktop/default template but with ESMobile, it uses the default language. Why is that?

Thanks,

Jackson
