New Tropic Marin Classic salt High alkalinity. 14 dKH?! Help

[d3ro]

So I just got a new pack of Tropic Marin classic salt. Its dKH is supposed to be 9-10 dKH, but when I mix it up it comes out to be 14 dKH!!!?!. I mixed and tossed that bag around when I first got it.
Ive made two batches with the same results. I measured and used the correct salt portions: ½ cup per gallon and my refractometer read 1.025. Ive tried two different buckets. Ive used two test kits (Hanna checker and api) which both came out to 14dKH.

Is there something im doing wrong? Bad batch? would appreciate the help.

....and I'm sure your test you're using is completely accurate

ive used two tests that give the exact same reading... as well as it was accurate a week ago when testing a different batch of water

I did a water change recently with TM Pro, and for no reason but curiosity decided to do parameter tests and my Alkalinity shot up to 15.3!!! Before the test I was at 11.7! Now I'm praying my corals don't take a hit, or tank crash until I can do another water change!
