Strange behaviour of "Load Stream Level" node

Hi There

I got the exact same strange thing. While other levels can be feeded from a separate source ( FName variable at least, or my intended level managing system), one level just won’t load. The print node right behind is called nevertheless.
To load this one weird level, i have to write the name of the level into the node, while other levles work as normal with FName variable.

Is there a known solution to this problem meanwhile, or do i miss something?
Also, i think of creating a new level and move all actors over as a workaround. Is this a viable (or the only) solution?

Thanks for the response.
