Reports aren't generating the proper URL

I have a large number of subdomains off of our main site, based on each customer's name: cust1.domain.com, cust2.domain.com, etc.

When I create a new report to analyze all of our traffic, the reported URL for each customer domain comes back misformed:

Instead of:
http://cust1.domain.com/blah/blah/blah
http://cust2.domain.com/blah/blah/blah

I get this in my reports:
http://domain.com/http://cust1.domain...
http://domain.com/http://cust2.domain...

This is causing difficultly pulling the data out of the report for proper handling by the accounts team. While it's fairly easy to just strip out the first portion for one or two reports, dealing with that on a full scale basis breaks down.

It does not break when the call is to a backend function and properly shows:

http://domain.com/program/variable
