Hello @MichaelL6234 ,
I apologize that this was happening. What method were you using to add contacts (type in one contact, type in or paste, upload from file) ?
I seemed to have been able to add that address, and it is located under a list called "TEST ctct."
If you continue to experience trouble with adding contacts, please feel free to email us a screenshot of how your screen appears. Our email is Social_Support(at)ConstantContact(dot)com.
