AW-2 Box 12 code W entry disappears

After I enter my W-2 Box 12 code C, D, DD and W data the C and W disappears after I go through my return. On the HSA entry it says that there are no contributions because box 12 was completed. When I return to box 12 the Code w data is no longer there (along with code c). I even tried saving immediately after entering the data.

Why does this happen?
