Payment Form improper autofill or prepopulation

When using Payment form, if not logged into Joomla as a user, form fields are blank and allow for user input to make a payment. If logged into joomla as certain users, the Payment form will pre populate fields with the wrong users information. I tried this on two different computers. Also tired different browers. Even tried clearing cookies, but same result.

The payment form is pulling information for a different use whom is not logged into joomla on that computer.

I have attached two pdfs. One without anyone logged in and the other with a Barry Smolowitz logged in, but as you can see it is pre populating with a Heather James.

Please advise.

Thank you
