One thing you can check is yours fresh tap water source/filtered water parameters.I had an identical issue once ( recently discovered trace amounts of ammonia)and it was from my 20 gallon storage bucket that I kept my RODI water in ,that ,was a source of ammonia,contamination,after the water was filtered.It wasn't the test kits fault.Poor husbandry on my part.
