Booking Window Not Working

[David3911]

This appears to be happening to others, but this particular scenerio seems to be unique to myself. I have booking window to 6 months (blocked beyond 6 months from todays date). However, when I tried to change the prices for those dates >6 months out, I had to make those dates "Available" to change the price. Now, I don't have the option to choose "Unavailable until [date] Based on your 6-month availability window". I've tried to set the booking window to 3 months, but it still keeps those dates as available (see image below). How can I force these dates to conform to the original 6 month booking window??
