Check your settings, you can choose for the needle to be in the center needle position instead of the left needle default setting. Or you could move the needle over using the stitch width button until it is centered maybe about 5.5 or 6.0, then touch the memory key and that will set the needle in the center position each time you go to that stitch. This is a common mistake so feel in good company. But, I don't know why your machine is now making a funny noise when you change the stitches.
