Anybody else notice that FRO doesn't work on first few lines of code?

After loading I lower feedrate down to 15-20% to make sure there are no surprises out of the gate.
What happens is the machine runs at 1$ until it hits the line of code sending the Z down to it's commanded position. FRO works OK from there.

Sample lines of code;

FRO won’t change G0 moves, you will need to use rapid rate override for that

Is there a button for that? FRO worked for rapids in Mach 3.
