Well. I test the MG with two different test kits and they all come to be around 1200. What am i missing?

The results you get are not typical of the new I.O. salt mix.
If mixed to a s.g. of 1.0264 (35ppt) then you should be finding that the new IO should be about 400 ppm and 1350 ppm magnesium or so.
If your s.g. is lower then your mag level will also be lower, but with the new salt, your s.g. would probably have to be around 1.023 to get mag levels of 1200.
To boost magnesium takes a lot more of whatever product you are using to boost it, than most people would expect, because the flake is mostly water. (hexahydrate)
