Creating supplier using Supplier Type "Supplier used to process expense payments to internal employ

Dear all,

We have an employee Müller in HR  who created an Expense report and for whom we want to create a new supplier.

Therefore we create a new supplier, using supplier type "Supplier used to process expense payments to internal employees". The supplier is imported into AP, except for the bank account information.

When we try to add the bank account manually the screen stalls when trying to enter the supplier countr, bank or branch. In fact it is not possible to enter a bank account. No error messages appear. Search windows do not pop up, but it is possible to navigate out of the page, as long we dont use the cancel button.
