This is probably a cartridge/arm Compliance issue. I had the same problem with a stone Koetsu, when I used the standard counterweight on the arm. When I put the heavier counterweight the song on the a.m. LP was flawless, no tracking issues at all.
If you know your arm mass, check the compliance with the Cartridge Resonance Evaluator on the VinylEngine.
