Are leaves actually "curling" or are they just reaching upwards? By upwards I mean the 2 leaf stems together look like a V as opposed to them forming a line thats parallel to the surface. The V is normal. If the leaf itself is actually curling then I would think something isn't right but even still it might self correct. Hope my explanation isn't too confusing.

The one thats stuck in the dirt is probably trying to free itself from the seed casing. Usually it will free itself. You can try to break the casing off but there's a fairly good chance that you'll damage/kill it.
