Ha ok, see it now.

I think what you're seeing could be the effect of deconvolution when star cores are burnt or over-exposed. CCD Stack in particular will punch out holes in the stars effectively taking them out from the inside out. Just do a quick star mask and put the original stars back on to the old ones.
