Yes to cable tension (have cables been replaced since 2014? install of the groupset?), and possible FD height above the big ring -- check this with crankarms parallel with the ground, as the teeth height I think varies by where they are on the ring relative to the crankarm.
Hi, correct, the chain often goes over the front ring when shifting into the big ring. I haven't changed my cables ever (6000 miles approx on them with lots of shifting-SF bay area riding). Maybe getting a high grade tune up and cable replacement is the best call (worried about doing the cables on my own).
