Retire pay amount incorrect due to SBP

So I just seen my net amount after taxes and it’s totally incorrect. They are taking out 226.53 for the SBP for a spouse instead of 10.00 for my son. I am not married never been married and the paperwork doesn’t have a spouse listed how incompetent can DFAS be when it clearly shows my son only and there’s no name on the spouse line. Has anyone experience this and how can this be fixed because this is ridiculous from them losing my paperwork to being told fifty million things.
