Companion frozen mandibles and precision

So first off all the frozen mandibles ant spirit cost is bugged. i have enough spirit to summon but he wont auto summon, i have to disable and enable another spirit skill to make ant summon. secondly dps calculation is bugged when i dont leave 10 free spirit. Example: precision 1 lands me at 2325 accuracy rating and 10 leftover spirit. Precision 2 lands me at 1922 when it should be 20% more than 2325.
