CellAssign not working correctly

Hi guys. I’m using a CellAssign to label cell types in a Human Choroid Plexus Sample based on the marker genes from a labelled mouse choroid plexus sample. I have managed to get CellAssign to run and label the cells in the human sample but I am missing an entire celltype in the final output. There is a huge chunk of cells labelled “other”, but I know for a fact that the cell type that is missing does appear in the human sample. I’m wondering how I can tweak CellAssign to fix this?
