When trying to add a supporting document using the filter in the Add Supporting Documents pop-up window, the user cannot see the value they are looking for.
The drop-down list displayed in the filter is not exclusive but is limited to displaying only some values.
After selecting the filter, start typing in the value that you are looking for. Example: Regulatory
If filtering on Document Type, the value is displayed regardless of the fact that it is not visible in the drop-down list.
