You should certainly look into what is causing these problems; other things
may also be wrong.

We would need more information. The lack of box information suggests that
maybe you didn't set the box in tleap: did you use setBox, or solvateBox,
solvateOct? Those are the most common commands that set the box info.
Missing coordinates might arise from having duplicate atom names within a
residue. But since we don't know what commands you gave to tleap, and don't
have any details of what is "wrong" with the inpcrd file, it's hard to give
much good advice.
