The H-bond plugin never catches any H-bond information from that capping group. My guess is the capping group is considered as a separate entity (not part of the peptide). Any insight would be appreciated.

It's a VMD question, so that's the appropriate forum.
You can easily do H-bond analysis in GROMACS with gmx hbond, and it will
consider all relevant groups. If VMD has some limitation or issue with
what it defines as H-bond donors or acceptors, again that is their issue.
