Derivative and dt trouble

Hello everybody. I would ask you why if I use the Derivative belonging to the Time Domain Math (it concerns dynamic data type) I can subctract a waveform with an another one keeping the same dt and why,on the other hand, if I use the "normal and typical" Derivative  I cannot do the same subtraction due to "a different dt between the two waveforms" Error.

Thank you in advance.

Moreover, I checked the dt values of the two waveforms: they are the same.
