Camera issues

[RM6SS62]

Hello friends, I have a decent experience with UE but just starting with this plugin.
I did follow the setup process exactly as it is described and found some problems with the camera.

1- Zoom doesn't work (ZoomCamera is bound to Mouse Wheel Axis).
2- Initially camera movement is ok, but when it's rotated (by holding RMB and moving the mouse in either axes) the axes mess up.
3- I don't seem to be able to modify the initial camera location and rotation, any change I make in the camera component of the pawn is not reflected and the camera starts always in the same position/angle.

Also I found Q and Space move the camera along the Z axis even when I never bound those keys.

Engine version is 5.0.3

Thanks in advance for any help.

Edit: Dropping a player start in the world fixed all the problems.
