Conference Bridge module not loading

Whenever the PBX server gets rebooted the conference bridge module does not load.
if I run "module load app_confbridge.so" i get the error message "Could not find option suitable for category 'admin_menu' named '#' at line 39 of /etc/asterisk/confbridge_additional.conf"
Screenshot of the error and the confbridge_additonal.conf attached.

The workaround that I have to do every time this happens is to edit the confgridge_additional.conf and remove the backslash on line 39 and line 61. This produces a warning when loading the module, but at the end it loads.
