lowest CAS

I was playing RTW with my new greek warrior unit when i noticed he was standing on 2 triangle shaped legs, same where true with his arms, i figured out it was because they where using the lowest CAS, i tried upping my graphics and they are still the same,

Could i just replace the lowest CAS file with the low one?

ex-
model_flexi_m data/models_unit/unit_roman_hastati_low.cas, 40
model_flexi data/models_unit/unit_roman_hastati_lowest.cas, max



model_flexi_m data/models_unit/unit_roman_hastati_low.cas, 40
model_flexi data/models_unit/unit_roman_hastati_low.cas, max
