Sometimes I have seen tack rags that have ended up causing fisheye problems before.
This would be due to the "glue" residue on the tack rag getting transferred to the surface.
I've sometimes CAREFULLY used something more aggressive like lacquer thinner on the trouble spot areas and then re-cleaned with the prep wash - hard to do with fresh paint!
I'd clean the area, scuff the paint and let it sit open a couple of days open to allow the solvents to escape, clean again and put a sealer on it.
Keep the first couple of coats lighter to see if you get a reaction again - make sure you allow the recommended flash time between coats.
