Billing Info Not Saving / Reverting to Shipping Info

[adam2003w]

I have an error with a site.

Error: When a customer enters their shipping & billing info into their account and saves it, the billing info reverts to the shipping info.

Where: Account & Checkout pages

Miva Version: Miva Production Release 6, Miva Merchant Engine v5.06, Database API MySQL.

Does anyone know how to fix this or what may be the issue?

Nevermind. I had the billing set to "hidden" in the admin. Setting it to "optional" resolved the problem.
