Q&A - Where does the "Website" field in the QA User Details generate from?

Hi -

We use BuddyPress, Membership Premier, and Q&A, and I can't figure out where the "Website" field is coming from on the member's Q&A Details that appear as shown in the attached screen shot.

We ask for a website in our Extended Profile fields within BuddyPress. So this Q&A field is not only redundant but also empty for our users.

Can it be removed/hidden?

Thanks for your help!

James
