Month View page missing Background image

Dear Events Calendar team,

My events page is working perfectly fine with the plugin background manager:

http://vda-bezirk01.de/?post_type=tribe_events

Once I switch to month view, the background is missing:
http://vda-bezirk01.de/events/monat/

I tried to mess around with the views folders in my theme and the month.php in it but I’m not that professional to get it working.

What can I do?

regards,

Robert
