I'm really not sure what your desired goal is, but this is what I see:
1. You have one instance of a bullet in your layout. Since the bullet sprite has a bullet behavior, it immediately moves right (it's starting angle) as soon as the layout starts, and ultimately collides with a dest sprite.
2. When the bullet hits the dest sprite, you have the player sprite's position set to the bullet's location, which is why the player appears to "jump".
Again, I'm not sure what your goal is, but it may be simple as adding an action on the start of layout to destroy the existing bullet sprite.
