I'll speculate this is one of your first bikes of that caliber, so take what I'm saying in that context. Minor shifting issues are normal with all bikes as cables and components settle in, then as they wear down. Minor, tweaking, following a procedure, not random changes are par for the course. You should be able to have the LBS tweak the cable tension, or better yet learn to do it yourself.
First, is it the Front or Rear derailleur that is giving you problems? Next, shifting up is going to a harder faster gear. So that would be larger chainring on the FD, smaller cogs on the RD. Which is it?
Loose cables on the FD will interfere with shifting up into the large chainring.
Overly tight cables on the RD may interfere with shifting into the small cogs.
