You'r OK they are not growing the wrong way. Leave it alone. The root will about turn itself and point down, once down an inch or so it will start pushing the seed shell up out of the soil and it is that action that usually knocks the seed shell off as it's working the sprout above soil.
Ideally you want to sow the seed so that the root tip comes out the top of the seed so that it can turn down but as said above, nature doesn't always land the right way and most still survive.
