The call is usually followed by the function or function block number right after the CALL (i.e. CALL FC6. You won't be able to download it until the red parts are removed or fixed.

The view shown in OB1 is the statement list that exists "behind" every block call. In your example FB85 is being called. This view is shown when the editor has lost the interface information associated with the block - does FB85 exist in your project ?

Here's an example of a call a call to an FB giving the nice editor view, followed by the STL view when the FB has been deleted and then only OB1 uploaded from the plc to the project:
