Welcome to the board OP 
I have created your own thread on this as the one you were posting in is nearly a year old. I changed the title and left everything else intact. I am also moving the new thread to the main CC forum.

Welcome to myFICO!
Assuming there's not been a change with the functionality of the Overstock SCT, you'll want to make sure your name and address are entered exactly as they are on your credit bureau reports.
In my case I have a suffix, and if I leave that off my last name I don't get the pop-up (when there's not a place for it - and there's usually not - I add it to my last name). Equally important is to make sure you address is an exact match. My address includes 'Highway'; although my mail arrives just fine if I put 'Hwy' if I use this on a SCT site I don't get the pop-up... it's that picky (or at least it was in the past).
In most cases, the address with the credit bureaus will be how the USPS has it 'standardized'... to check your own you can click here: https://tools.usps.com/go/ZipLookupAction!input.action. That site is a ZIP code lookup tool, but it will also show you your standardized address as well.
Hope this helps! 
Got mine via the SCT. Started off low but up to $1500 now. Just keep trying.
