Last night I was able to duplicate it by turning lights on very slowly until I saw a light flash and they started going from Right to Left.

Funny thing was the 2nd time I did it they went from Left to Right, and 3rd time went back to Right to Left. crazy

That's an interesting effect you noted there. I suspect that you're substantially beyond 90 degrees of phase delay and just barely above the voltage needed to feed driver output. The input impedance of each lamp would change during the seconds that it takes to charge up to the point where the LEDs are pulsed. It makes sense that they would fall into sequence and balance out, rather than all draw peak charging currents at once.

It is best to choose a flicker-free LED driver. You can check this article to learn How to select an LED driver.
