ModGui transport

Hi
just a quick question - is it expected behaviour that the play button in the MOD-UI will not latch to run- even if i select internal for the sync mode?
I am trying to patch together a sequenced gate pedalboard but can’t seem to get an internal clock.
Also the midi clock generator plugin doesn’t run (clock display on the clock plugin ui doesn’t change)
If i select Ableton link i can get the tempo to sync but the MOD-UI transport won’t change from stopped.
cheers
Rod
