The new mint bills feature shows a duplicate Kohl's bill, but there is only one Kohl's account configured.
When I review my due bills, from the new Bills functionality, the iOS app displays two Kohl's bills, both for the same amount, same due date; however, I've only one Kohl's account associated with my mint.com account.
(UPDATE: I have since logged into the web portal and only one Kohl's Bill is listed, as expected. I've returned to the iOS app and again confirmed two Kohl's accounts are present and taken a screenshot).
I'm happy to upload the screenshot, though it is displaying balances and the last four digits of my cards (I would black them out, but then that "corrupts" the integrity of any screenshot I took)
