Reply to S4/Traktor Beatgridding Skipping & Delay Problem

Don't know if this has happened to anyone in Traktor but ever since I downloaded and used Ean's beatgrid mapping, when i start to play the songs and practice mixing afterwards on the songs i setup and locked using his mapping they start to skip & delay. The only thing that has helped & stopped that from happening is by not using either the Sync function(either beatsync or tempo). But let's be honest the sync function on the traktor is quick and easy way to bring the songs together. Is there any suggestions ? thanks
