Looks like a match.

 

With samples taken the same time, a little closer but still not the same.

Strange.

 

Guess I will just have to invest in another brand of tests to get a different opinion.(scratch)

Did you try using the tubes with the opposite test kits to rule out the tubes being contaminated? New tubes are cheap... I know at least one API kit will leave a residue that throws the other tests but can't remember which it is so I keep them labeled and don't use each tube for any other kit.
