Why halos on bright stars with green and OIII only?

As per the title, I seem to be getting halos around bright stars with the Baader 36mm unmounted green filter and the 12nm QHY OIII filter in the 36 unmounted. None of the others show it. Also, I never seemed to get any halos with the QHY LRGB filters that I just replaced.

I have heard and read on the Baader site to turn the filters against the arrows that are on the edge to combat halos and was wondering if anyone has had any experience with this?
