I am going through the same problem now and we also had this issue at our previous address about 6 months ago. Unfortunately there is nothing you can do on your end. Your power levels seem OK but the upstream is a bit high. I was told by the most recent tech that 42-45 is the range you want your upstream to be at and close to 0 for the downstream. I would call another tech and keep having them come out until they fix their infrastructure. It took a third call before they finally sent out a senior technician that was able to start the ball rolling to fix the issue. They had to put a monitoring request on my location and the node which must have eventually cause them to fix it because the problem went away at our old address. But here we are again at a new house having the same problem. I have a second tech coming Saturday, we'll see what they do from then.
