Cant apply axial load

Im trying to insert particle into a cylindrical container and apply axial load on it over the top plate. But it is showing error
ERROR: Fix wall/gran (id geometry): More than one wall of type 'mesh' is not supported (/build/buildd/liggghts-3.0.3+repack/src/fix_wall_gran.cpp:505)
