Whats causing this Halo ?

Anyone got ideas what might be causing a Halo around a bright star on Green and Blue Filters ?

I took some 10 min exposures tonight gathering color data and I noticed my Green and Blue filter exposures had a bright halo around one of the saturated stars.

I have attached a picture.

The red filter does not have this. They are parfocal Astrodon Gen 1 filters.
