Insteon 2477 Dimmer Flashing Red

A number of my Insteon 2477 dimmers flash red when I turn them on or off. I think it has to do with the fact that when I ask to manage syncs, it shows a number of non-erasable links but I am not sure. How would I get rid of the red flashes.

Best approach generally would be to factory reset them then re-sync them in Indigo (which will re-write automatically all the links you created in Indigo for it).
