29% moisture hay not getting hot?

Saturday we had a rain shower while baling so we stopped hay was running 12-14% moisture. So after the storm passed we waited 2 hours and baled the rest at 22% moisture no preservatives used I know to wet . Any way the hay is reading 29% moisture now but bale temperatures is in low 70 degrees so it’s not heating as expected. Is the hay not heating because it was dry before or will it still heat up . I would like to unload wagons but am Leary of putting in the barn. There are about 450 bales and I hate to do double work.
