Not able to delete/add a bank account

Hi,
I'd need to edit a bank account.
Since, according to the documentation, this is not possible (not in a straightforward way at least), I'd need to delete the existing (and already approved, by the way) bank account and create a new one.

When trying to do that, though, I stumbled on to a couple of issues:
1) there's currently no option/button to add another bank account
2) trying to delete the existing bank account triggers the following errors: "You cannot delete this bank account because you have funding sources connected to it."

Any workaround?
