Metronome still plays though toggled off

Hi, I am using Synth 5 as ARA bridge in Fender Studio 8.1 (Studio One).Synth V version 2.2.1
The metronome plays during the scope of the green frame (whatever that is called) even though I have toggled it off.
The metronome playback is confined to the scope of the frame so, when I resize the rendered frame, that affects where the metronome plays.
Muting the dummy/placeholder audio track silences the click, so that’s a good workaround. But still developers might want to look into what’s causing it.
