Bookable Calendar Opening disabled has no effect

Hello everyone,

in ReadMe it says "**Status:** Easy turn it on/off for booking". But when I set the status for a Calendar Opening to disabled, it has no effect on the visibility of bookable appointments in the public calendar view.

Since no one else seems to be having this issue, I think I'm missing something. I've repeatedly checked the permissions and tried to find the place in the code (query in renderer.php?) where visibility is controlled, but without success.

I would be very grateful for any advice!
Thanks in advance!
