Bug when someone changes bank account

I changed my bank account address for sepa and wire transfers (for both I use the same bank account). When I change the bank account address for wire transfers I can also change the other bank informations (SWIFT/BIC, location of the agency) but I can’t change those additional informations when I change bank account address for sepa transfers. I don’t know if those other informations are necessary for sepa transfers. What I know is that when I try to withdraw money by sepa transfers, bitstamp do some very frustrating things:

1. shows on screen the correct bank account address together with the old, outdated bank account informations
2. asks me to check if everything is correct (of course not!)
3. if something is not correct, invites me to click a link in order to fix the informations
4. the link sends me to the same page I previously used to change the bank account for sepa transfers (and, of course, you can’t change the additional informations from there)

Please, fix this annoying bug
