Unable to see data on the Tabs; source, destination etc

Unable to see data on the Tabs; source, destination etc

Hello,
 
When i open a IP group you can specify wich tab you want to see. For example source or destination.
But when i clock on them i always get en empty screen or an error.
Only ther datatransfer tab shows me information. I attached three images with the "errors" in it.

 
How can i solve this?
