Very often the various websites and search engines that pick up and features listing information have incomplete or incorrect information. Also, I have found that there is a time delay that can range from a day or two up to a couple of weeks or more. I am certain that what you saw was probably due to some glitch in the system. Based upon the information I obtained from the Memphis Area Association of Realtors' MLS system, you home is showing as closed and is NOT, nor was it ever in the system as available for sale through Mr. Anderson or anyone else subsequent to your purchase.
I hope this answers all your question(s) regarding this matter. Congratulations on your home purchase. I hope you enjoy many years of happiness in your home.
