Display value from config in UI fields when config.GetValue processors is used

[davidferlay]

Observed

• Values from config are not displayed in UI fields when config.GetValue processors is used
• It's a bit misleading that value is UI differ from value that will be used when executing action

Expected

• Values from config should be displayed in UI fields when config.GetValue processors is used
• That way, user will be able to see values that will be used when action is executed
