Trouble Starting A Scene

[Heromaster]

I have some serious trouble starting a scene through the Story Manager.

 

This works:

 

This doesn't:

 

As soon as I change it this way the quest will not be started anymore. Papyrus log doesn't tell me any errors, so does not 'Warn on alias fill failure'.

 

A sqv APPS_S01 shows that no alias has been filled and that the quest is in the state Stopped. Where lies the error?

 

Update: Somehow, after I changed this back again now it tells me something different.

 

sqv APPS_S01 Output:

 

And the info from Papyrus log:

 

 

[04/29/2014 - 01:23:28PM] ERROR:  (1201479C): cannot start scene because its parent quest was not running.

Have you checked that you set the scene's parent quest correctly?

The scene itself lies in the quest that is started through the Story Manager. And that quest is running as you can see on the last screenshot. That should be the parent quest, shouldn't it? If not, how can I set the parent quest?

Any other ideas how to solve this problem?
