variables are not changing in batch email

I have not be able to get the variables to change each time i send a batch email out to multiple LP prospects. 
Tried to save a template.  All the fields are setup correctly. Sending individual emails the variable (First Name) populates correctly.

There is even a notice right a way pop up stated: "Note: Variable personalization for this email will be applied using the first existing recipient's details."

Any help?
thank you,
Vincent
