The SQP method encountered errors when displaying each phase of particles

Hello, everyone!
Simulate two types of particles in MFIX, and when you want to display each type of particle in the vtk interface, it was originally a spherical particle, but in MFIX, nonspherical particles are displayed. (1.9 MB)
I would like to ask everyone to help me find out which one has the problem. Thank you!

Did you manually edit the .mfx file outside of the GUI? I only see two vtk regions in the GUI while you have four in the .mfx file

Thank you for your reply! @jeff.dietiker
I manually edited vtk outputs 3 and 4, otherwise I don’t know what good method is to display particles for each phase. Do you have any good method to display particles for each phase separately? Thank you for your help!
