Eeek! Not good. If I didn't know better, I'd say the rods are too short... It looks like first one pops out, and then engages again, the then the other one goes. Either the magnets aren't strong enough, or perhaps the movement is just too much for it atm.
On some of the later versions of flux studio (somewhere after v0.8.3), you can disable the movement test, and see how that goes... maybe you can enabled it after the machine has a few prints under it's belt and it's started wearing itself in? It might be able worth tweaking the machine radius option in the machine preferences... maybe dropping it a couple of mm will stop it? If you do try it, make sure you write down the initial number if it is different, and let us know if it does affect the movement test
