Keep them moist and they will probably work themselves out...if they don't after a few days you may GENTLY try to help them...
Soaking and planting a little deeper will prevent very many from happening in the future for ya. Out of maybe 120 sprouts so far this year I had three.
Surprisingly I had an Atomic Starfish come up with the seed still on it, the cotyledon was all sorts of mangled, yet it is now my strongest from this variety.
