Wondering what the protocol is for ECM tables shown in a vehicles readout that when slewed, do nothing?

Is it basically "that's how it is, tough luck"?

Or can it be looked into and possibly fixed so the table slew actually works?

I don't have my laptop accessable, but it's essentially a MAP/RPM based PE adder. I'm targeting a specific window and no matter what I input, there is zero change to fueling after writing the cal?
