I believe it was the cleaning residue left behind not thoroughly rinse off that became the issue. You may start all over again to remove the “extra waxiness” with Prep-4.4 > Clean-3.8 > Rinse-3.0 (make sure all residue of Prep-4.4 and Clean-3.8 is removed off with Rinse-3.0), proceed with Hydrator-3.3 > Fatliquor-5.0 > Hydrator-3.3 let it dry then Proceed with WaxEffect-8.6.
