k14, p2, k2, p2, (k12,p2, k2, p2) across to last 12 sts, k14.
Is that exactly how it's written or did you type a number wrong. You can't knit across to the last 12 sts, then k14.
However, I would say that you repeat what's in the () because that would make each end of the row mirror each other --
Start - k14, p2, k2, p2..... and end with p2, k2, p2, k14
