Problem with camera, moving objects

Hi everyone,
could anyone please help me? I have a problem with unreal engine and unreal tournament editor.
When it was updated, I started to have a problem with camera. When I build a wall or something and then I want to move around with the camera (I don’t push the button play), the objects which I built, they are moving. So instead of moving with camera, I am moving with the objects. Does anyone know what to do with it?
Thank you in advance
