Error setting up monitors in MFIX-GUI-20.1.0

Dear MFIX development team,
I have picked up another bug in MFIX-GUI-20.1.0 for setting up monitors in MFIX-DEM. There is no window pane for selecting particle data type

.

Can yo share the mfx file?

Sure onlyjussscp_dem.mfx (21.2 KB) but I managed to resolve this one. The monitor I am interest in is the volume weighted average for particle velocity but if selected in the drop down list then the particle properties do not appear. However choosing another monitor type like standard deviation activates the particle data to write. From there I edit the monitor type to volume weighted average.
Secondly newly introduced tpkkv drag model in MFXI-GUI-20.1.0 gives a run error when selected i.e ERROR des\drag_gp_des.f:184. However passing on the drag model as a user defined drag in MFIX-GUI-19.3.1 seems to work fine.
