Setting supplier bank account as active

Summary:

One of users is trying to set a bank account as active so it can be selected to pay the invoice to. The following actions did not help:

1. There was an inactive date there. She deleted this and it was approved.
2. She added an inactive date far into the future and it was approved.

She has now deleted the inactive date again.
You can see in the screen shots the bank account is still showing an inactive date, even though this is blank when you click into the details.
Has anyone else had this issue and how was it resolved?
