I suspect that your outputEnergies period (e.g., 10) is not a multiple of
your fullElectFrequency period (e.g., 4). The logic that avoids the extra
math to calculate ELECT energies that the user never sees doesn't
anticipate this, so half of the energy output are missing the long-range
ELECT energy component. The other energy terms should be OK.
Minimization uses energies directly and therefore always calculates them.
