How did the sulphate ion get into your bath? If it did not come form outside, then it is a by-product of the sulfamate ion dissociation. Then you also have ammonia ⇦ this on eBay or Amazon [affil links] ion present. Both ions are really problem. As I do not know or live in your country, it is easy for me to say, but I would make up a new bath.
