Problems with spawning obstacles and pickups from endless runner tutorial!

Hello everyone, I watched endless runner tutorial and tried to do the same, but my obstacles and pickup item don’t spawn! I have checked all blueprints, tried to add “spawn actor from class” instead of “add child component”, but it didn’t help. Please, help, because I have no idea what else I can do.
Here is a video links:

Tried to connect same functions from the forth screenshot with origin - event begin play, it worked, so I cant understand why it works with event and doesnt work with function “construction script”
