UNABLE TO SET “Minimum length of stay”

New website user here, trying to set a bulk, "Minimum length of stay” to 4 days minimum for ANY day booked...I have followed the following information on the below page, but it is not working...Any instructions/tips would be greatly appreciated. 


"The minimum length of stay is the minimum number of nights guests can book a stay, while the maximum length of stay is the maximum number of nights guests can book a stay.

Depending on your property type, one of the following options will be available.

If you have a calendar showing 30 days at once, you can only set the minimum length of stay by following these steps:

  1. Under the “Rates & Availability” tab, click Calendar (or the relevant room name).
  2. Click a date (or dates).
  3. Under “Minimum length of stay” on the right-hand side of the page, there’s a drop-down menu. Choose how many nights you’d like this to be.
  4. Click Save when you’re done.
