That’s really weird. Btw I have the same RODRET Dimmer with the same firmware and luckily no issues at all. But based on this forum thread, it might happen if you paired them in close distance to the light - How to link Ikea Dimmer Switch with a Zigbee Bulb - #12 by MMR
So I would suggest to start with reset and re-adding them back ensuring you keep it away from other bulbs (or keep those bulbs turned off), simply reset them and then add them via REPAIR.
If it will not help, not sure but maybe you would need to reset bulb as well.
