Kaons are not backtracked to PFP

[bear-is-asleep]

Description

I was looking at a small sample of neutrino samples, all containing kaons. The genie event record rec.mc.nu.prim indicates there are kaons in every event from the interaction, but not a single PFP is backtracked to a kaon in rec.slc.reco.pfp.trk.truth.p.kaon. The kaons also have non-negligible energy, so I'd expect at least one to be reconstructed. I've attached plots and a cout (in messages.log) of the PDGs of the true PFP pdgs and the pdgs of all the primaries from the event record.

Reproducability

For reproducibility I've made a github repo with steps - https://github.com/bear-is-asleep/kaon_cafana/tree/main
