Katie...you aren't doing anything wrong. I have also noticed a problem with the RETURN POLICY section on Auctiva. For several weeks I have entered our return policy on the item list page with NO problems at all. Suddenly today I see that no matter what I type in as my return policy (7 days/money back in my case) the system reverts to 3 days/exchange. I had to go into eBay & manually change it back to 7/money back on the items I listed. That was A PAIN & I urge Auctiva to fix this SOON!
I might also add that I tried making an entirely new Checkout Profile with 7/money back but it still reverts to 3/exchange when I try doing a new listing.
