670G and its automatic mode

As you know the 670G has an automatic mode that in theory leads you to 120 mg/dl and manages the basal as you need it ... well, the fact is that, after two months with it, at night, it sends me byAbove 175 (even correcting at the middle of the night) and that I wake up at 5 to go to work, imagine the heat and thirst with which I get up.During the morning his work is doing well but after the snack, he sends me again to Hiper, I correct in the afternoon, I arrive well at dinner and start again.My endocrine recommended me to put more HC than I am going to eat in the snack so that it would not go up much but what happens?I put more bolus, but she puts less basal and we end up in hyper equally.
It is very frustrating to see that it goes up and up and you can not put a corrector bolus because there is an active insulin (and you cannot lie, putting that you are going to eat so that Bolo puts it because you end up in hypo almost certainly).
The ones who use it, any recommendation?

To have everything focused under the same thread and that people are more comfortable to search, find information and not have a nonsense of open threads with the same possible issues or observations we continue in the thread already open for the Medtronic 670.
Thank you.
