they're not really an error, just some warnings
instead start with empty save files, you downloaded save files already created, so in this case there's a few items on your spherestatics.scp which doesn't exist on your scripts folder, making the sphere show this error "invalid worlditem" at server startup. So you must add these scripts, or just remove these items from your spherestatics

the other error "mount memory not equipped on correct layer", as the message already said, is because there's a mount memory not equipped on the correct layer. Usually sphere automatically remove these items when the error appear so there's nothing to worry if this message only appeared a single time
