There's a lot of info on the forum about this issue. To summarise : firstly make sure the shift lever is adjusted to suit your foot position on the peg. I would recommend that the best solution is usually to adjust the lever so that it's a bit "lower" which will give you a more positive throw when changing gears. secondly, when you are shifting (DQS or manual clutch) make sure it's a "positive" action with a little bit of authority. Don't "squib" the gearshift you need to be reasonable forceful. Keep in mind your bike is new and new gearboxes are notoriously "notchy" - it should improve with time
