You will only see activity in the modulator center line, if a modulator like the Macro 1 is set to modulate something, so the modulation amount is'nt zero, and the modulation is'nt muted.
To me it look like you actually have'nt assigned Macro 1 to modulate any parameter or you have muted the modulation.
Be sure the Macro is set to a modulation amount and the modulation is'nt muted.
Please attach a screenshot of the parameters you see in the center line, when you click on M1, if this does'nt help.
Also please tell, if you have the issue when you use Pigments as standalone application.
