Missing language keys: _sys_module_*

Any idea where I can find the language text for these items? I've looked in the database as well as the main language file but still cannot find them. They are shown in the member_privacy.php page and currently simply show the language keys below.  This is a fresh install of 7.1.0.

_sys_module_events
_sys_module_groups
_sys_module_photos
_sys_module_poll
_sys_module_simple_messenger
_sys_module_videos
 

 I've tried recompiling the language for each individual module too.

Answer (courtesy of AntonLV):
The issue with language keys on Member Privacy page is a bug in D7.1.0 and should be fixe by BoonEx.

It was already reported and there is a ticket for the problem in the BoonEx Trac. To fix it locally on your site, you need to add all these language keys via admin panel -> settings -> Language settings.
