Suspension demands extra steps in cable measurement. Whether assembling on the floor or in a stand, the brake and gear cables must be measured long enough to allow for the full travel range without the cable never being tugged on. Odds are you installed this cable with the bike on the floor, this time hang the bike and let the fork fully extend before measuring and cutting the cable.
BTW- this is the first I've seen this problem on the front. Usually it's rear swing arms that when fully compressed, say on a bump or hard landing, compress fully and pull the gear wire causing ghost shifting.
