Number of cells after cellbender much more than number of cells from cellranger (filtered)

[pc2001]

Hi,

I am running CellBender 0.3.0 with default parameters. In one sample, the number of cells after processing through cellbender (N ~ 67000) are considerably more than output from cellranger (N ~ 9600 for filtered).
command:
cellbender remove-background --input raw_feature_bc_matrix.h5 --output ${FASTQ.ID}.cellbender.h5
The cellbender metrics, where most of the barcodes are considered to have cells looks like:

Thanks!
