As Freddy said, the movement ring (and movement) have only one possible orientation: the stem hole has to be lined up at 3, and the movement ring needs to be installed on the movement such that the stem goes through the cutout. There is no indexing involved.
It sounds like your gen dial, which doesn't have feet, is rotating on your movement. This is a different problem. Your hands and dial need to come off, and the dial needs to be remounted. This is why I use glue rather than dial dots on dials with no feet, to prevent this sort of problem.
