Stacking up of admin email niotifications

Hi, i contacted you recently regarding stacking up of the admin email notifications. Back then it looked like that by adding some of the listed below format strings to “Admin Notification From Name” field as well as “New Submission Notification Subject” field will solve the issue (because each email notification will have unique title and subject line. But it looks like that email notifications keep stacking up together.

%FORMNAME% : Replaced by the Form Name.
%SITENAME% : Replaced by the Site name.
%FNAME% : Replaced by the user's first name.
%LNAME% : Replaced by the user's last name.
%PHONE% : Replaced by the user's phone number.
%EMAIL% : Replaced by the user's email address.

Do you have any idea why it is happening?

Thanks
