I agree with Larry in that I think the stylus is sliding on the raised lip. That plus too low a setting of VTF could result in the observed problem. But I would also point out that the skating force does pull the stylus inward toward the label, so too much AS (which pulls in the opposite direction) would not be expected to be the cause of this problem. Maybe try increasing VTF by just a hair so as not to exceed the recommended max? And see that that does.
However, the skating force alone is usually not sufficient in magnitude to account for the observation, unless the tonearm is wildly misaligned. Think of it, zero anti-skate, which results in unopposed skating force, all other things being properly adjusted, does not cause the stylus to skip outer grooves per se. Moreover, the skating force is not maximal at the outermost grooves.
