Multi camera audio sync - Move button does nothing

In Linux Mint:

5 cameras, resources only, open in mixers, un-arm all tracks, move master track to right to ensure it's right most, set in and out points, select align mixers window, select master track audio, select the 4 non-master mixers,

click on Match.  POS values are all 94****.  Nudges are -.1 to -4.0.

Click on Apply first, the Move or just Move at this point?

Clicking on move next clears the nudges and nothing has moved.

Click on reset, select 4 non-master mixers, click on Apply, some video timelines repaint, click on Move, nothing has moved.

What am I miss understanding here?
