This even does happen with Amber :) So my guess is you correctly transferred the parameters, but stumbled upon an artefact. If you check the recent literature you may notice that many publications with Amber using K+ only employ minimal (neutralising) salt conditions as a workaround. At least this is what we did recently [1].
