Multicam clip not playing with timeline playhead

Let me state I've successfully edited multicam footage before in resolve but everytime I use it something comes up. It really needs to be revamped.

My situation is this. I'm making a music video where the clips are unsyncable through waveform and no timecode. So i manually aligned everything and converted a timeline to multicam clip, no issues there.

I put the clip in a new timeline and when scrubbing the playhead the multicam viewer does nothing.

Any reason it isn't scrubbing??

The Source Viewer has been placed into Multicam mode?
