I believe its because they are fundamentally different constants. Cv is under constant volume and Cp is under constant pressure, so they are different

These are considered to be fundamentally differnet constants, given and acquired through different sets of conditions. Cvm is under constant volume, while Cpm is under conditions of constant pressure.
