Hey @polarpam 
Ah I’m sorry for the confusion & hassle. That section of the add money home screen will show any pre-approved transfer you’ve setup along with any bank that you’ve recently made an easy transfer too.
So for your case even though you’ve revoked your pre-approved transfer with Halifax, your most recent easy transfer was to Halifax which is why we show that as an option.
The idea being that we’re providing customer quicker access to moving money from the banks they most commonly transfer money from. Sadly customers aren’t able to directly customise or edit this.
I hope that’s helped you understand what’s happening here.
Thanks
Lewis
