Bookings Global Availability

Hello. I’m using wcfm/woocommerce-bookings to run a Tour Booking System Marketplace at http://www.sanpedronline.cl
with the covid pandemic there are days that can not be booked. so i tried to do it through “Global Availability” as an admin, but the availability rules that I set does not take effect on the booking calendar. Then, I tried to do it logged as vendor, but the Global Availability Rules are not being Saved (it tells that it does, but if I refresh it does not)
The only thing that works is to do it product by product. but thats unpractical…
Any help?
(I loooooove wcfm by the way)
