aescripts + aeplugins

This is my first and only issue with your amazing product.  Making a plexus from light layers using textured sprites as the points.  When depth of field is applied I get a weird additive effect around any blurred points.  Has anyone seen this before.

It's only with the textured sprites.  Default dots blur perfectly.  I've tried many different things but none work.  Is this an issue that has come up before, and there is a work around for?

Thanks
