@David8211 When viewing your listing, indeed most of Oct, half of Nov. and some of Dec. shows as unavailable. Random dates blicked in Jan, Feb, and March.
Don't know if you have done anything to cause this or whether it's a tech glitch.
Go to your availability settings and make sure all is checked correctly, then try to unblock the dates from your calendar.
If that doesn't work, you'll have to contact customer service.
Open dates mysteriously showing as unavailable or vice versa isn't a rare issue.
