Dates keep randomly opening up on my hosting calendar

[Louise1574]

Does this happen to anyone else? Random dates in the future ( usually between 6-10 days) keep opening up in my calendar as being available.  I am not opening them up and no one else has access to my account. Once or twice someone books for these dates and i them have to cancel them. Is this happening to anyone else? Thanks, Lewis

What is exactly "the future" ?

Is there a relation with your setting  for "availability window" ?

Hiya Emiel, Usually about 3 months away. Oh!! that has made me think. I have my "availibility window" set to 3 months. I'll change it to "dates unavailable by default" I think that may help. Thanks for the inspiration. L
