Status changes to properties for sale happen constantly. It is very difficult for every website to keep its information current. With the number of properties, and constant information changes I'm sure you can see the potential problem with accurate information.
What you need to do is either call or email the listing agent to verify the status of the property. Or, What I would suggest is work with a Buyers Agent who has access to the local MLX to keep you informed on what is going on. Typically Working with a Buyers agent is provided at NO COST to the client. So at no cost you would be receiving accurate information and professional guidance.
