It looks as though you need to check the "stick to edge" box for your Buttons. I would also remove all the black edges too as this makes it look like the screen isn't fitting to the device. Try to replace them with more of your sky/space background. The Main Menu image is getting clipped because it's a static image. Ideally you want less details around the edges to account for fitting to multiple devices as clipping/revealing extra areas will always occur when building for multiple screensizes. Having said that, I'm not sure whats going on with the the Levels so there could be a bug with Auto-fit for Landscape devices. For a quicker response and a fix I'd send all this to Support@Buildbox.com @Andy will get back to you pretty quick.
