AMBER: antechamber - missing improper torsions

Dear Amber users/developers,

using antechamber (of amber8) I have prepared prepin and frcmod files for
various small molecules. Using these files with leap I noticed lots of
warnings in the leap.log file like e.g.:

No sp2 improper torsion term for c2-ha-c2-c3
No sp2 improper torsion term for ca-ha-ca-ca

Can I safely ignore such warnings or am I supposed to add such parameters
to the frcmod file?

Thanks very much!
