Bookings' "Different Availability for a Date Range" allows to set only 6 weeks ahead

My schedule changes often, therefore I need to provide different availability weekly.

I do this by adding weekly hours in the Default in "Availability During these weeks

Currently, Bookings only allows me to set my future availability 6 weeks in advance.  On the 7th week, under Availability during these dates, I can only choose "Bookable when staff are free," or "Not Bookable."

How do I set up Bookings to post my availability out to 120 days or longer?

These are my current settings.

1. In the business information section, business hours are set to “Day Off” daily.

2. Under each service, I have the default scheduling policy toggle on.

3. Under Staff In my profile, I have business hours set to off on all days.

4. Under the booking page, default scheduling policy,  I set the maximum lead time to be 120 days, General availability to "Bookable when staff are free," and weekly customized times; however, I can only add six weeks, about 45 days in advance
