No box for solid volume fraction in the MASS OUTFLOW condition

I am trying to setup a mass outflow condition at the outlet for a MPPIC simulation.

However, in the solid section there is only space to enter the mass flow rate (volume flow rate or velocity) but not anything to enter the solid volume fraction (shown below)

However, when I run this case, it shows an error that the no EP_G or EP_S was defined at the boundary.

But I cannot define the EP_G or EP_S at the boundary because there is no section to do it

BC_EP_(S/G) is available only for pressure inflow/outflow not mass outflow

Thanks for the reply.
However, when I run the case with mass outflow condition. MFIX mentions that if BC_mass_outflow is mentioned that EP_G needs to be mentioned.

Thus, my question
