Harvest tec 496 moisture questions

I just bought a case ih lbx 332 big square valet with a model 496 harvest tec applicator on it I started to ball alfalfa and it said the moisture was in the low 30 percent range I bought a 5 gal bucket tester and said the moisture was between 14 and 17 percent the hay had been mowed 4 days earlier raked the second day and had good sunny days on it I've contacted several dealers and they said the moisture sensors are never wrong. The alfalfa was dry to touch and had started to loose its color. Im using new Holland hay preserver and don't want to waste to much but don't want molded hay. What should I do
