How to remove a color from a date

Hi all,

I marked a date as “reserved” but now need it to be available again. Is there a way to do this without having to make a specific color on the legend represent “available”? I would like to avoid having to mark so many dates as available.

On the “Availability Calendar” page where all the dates are listed, only 20 show even though I’ve marked 140 or so one way or another. Is there a secret to getting all of the to show so I can simply find the one I need and delete it?

Thank you!
