Launch level from camera view

I have a level blueprint that let me place the player view on a cinema camera when the level loads but after 2 sec, it switches back to the firstpersoncharcater view (even if I delete that actor). I didn’t have that problem in a previous scene but now I can’t get the view to stick to the cinema camera actor!!!

Here’s my blueprint :

Any idea what I’m doing wrong?

That, I have same problem… I have no idea how.

I dunno what happened but now it’s working correctly and I haven’t changed or added anything to my scene. A bug?
Strange.
