ReconstructedChargedParticles Missing, but ReconstructedParticles Present In Output File

While testing on a small sample to take a look at the output on my own for a quick checking,

I noticed that the ReconstructedParticles data collection is present, but the ReconstructedChargedParticles collection is missing from the output file.

npsim:
npsim --compactFile ${DETECTOR_PATH}/epic_craterlake_10x130.xml --filter.tracker 'edep0' --outputFile dvpi0p_10_130_plus_1M_long_polarized_minus_ab_1.edm4hep.root --inputFiles /gpfs02/eic/jkim/DVpi0P/sim_data/dvpi0p_10_130_plus_1M_long_polarized_minus_ab.hepmc

EICrecon:
eicrecon -Pdd4hep:xml_files=${DETECTOR_PATH}/epic_craterlake_10x130.xml -Ppodio:output_file=dvpi0p_10_130_plus_1M_long_polarized_minus_ab_1.eicrecon.edm4eic.root dvpi0p_10_130_plus_1M_long_polarized_minus_ab_1.edm4hep.root

I'm confused. I see a ReconstructedChargedParticles collection in that eicrecon.edm4eic.root file:

The collection is empty but that's expected since the proton is probably going in the far forward direction, and the pi0 won't lead to charged tracks. There are entries in the ReconstructedParticles collection since the pi0 will lead to clusters which are added there.

Would the scattered electrons be saved in ReconstructedChargedParticles collection? I have been used ReconstructedChargedParticles collection to look at scattered electron. From what I understood, ReconstructedChargedParticles collection is to look at tracks and matching with clusters and is for charged particle obviously. And then leftover clusters are treated as neutral particles and added into ReconstructedParticles where all reconstructed particles are saved, except for far-forward reconstructed particles yet.
