Instant Ocean Salt Mix has "NITRATES"

1. Are you saying that if I wait 24 Hours, it will test 0ppm? if so I didn't know, an will do for now on, I usually wait about 8 to 10 hours.
2. Are you saying that I can't use my saltwater nitrate test kit, on fresh water, because when I test tap water with it, it shows nitrates, and when I test my RO water it doesn't, so that's telling me that I can!

I bet it shows fairly high nitrates for your tap, though. Last I checked, EPA limit is somewhere near 10ppm, 100x higher than you read from your saltwater.
I'm not sure exactly what the reagents are and thus can't tell you exactly what they'd do in tap, but I can say that tap water is no where near pure 0 TDS RO/DI. In any case, the nitrates you're seeing are so low that they're irrelevant. Having absolutely no nitrates in your tank would kill all of your photosynthetic corals; there is NO reason to fret over a reading of .05-.10. Hell, there's no reason to fret until it's near 5 and you're seeing algae issues or otherwise.
I have a hard time believing that hobbyist test kits are reliable enough to such precision. This really is a non-issue.
