Question In Pix4dmapper Example Dataset Quarry


I use the pix4dmapper to generate orthomosaic from Quarry Dataset. My result indicates that, on the scale bar, the higher elevtion(>583) of DSM appears to contains more areas than lower elevation contains. The color scale bar of DSM result on the pix4DCloud of this dataset shows the opposite. Is there something wrong I possibly made?

Can you provide the quality reports for both Mapper and Cloud? In addition, screenshots will be very useful to include.
