Bookings - request can't be completed

[MATTHEW BATCHELOR]

Trying to save the bookings page...

Also getting an error that makes no sense - Please make sure all dates across all service windows do not overlap with each other.  But I have nothing set up. I'm just trying to save the Bookings page.

I had the same issue.  I was able to resolve it by selecting the "Maximum Lead Time" to a future date.   For example, my "Maximum Lead Time" was set to 21 days but I set my custom Bookings calendar to a date 5 months from now.  Once I changed my "Maximum Lead Time" from 21 days to 150 days, I was able to save my Bookings.  Hope this helps.
