The pre-AP cars display it differently, but I just wanted to mention that we get regen-limited between 45 kW and 60 kW without any dashed line. Thus, there is a dashed line for regen limited up to 45 kW. Once it is over 45 (but even before it gets to 60 kW), the dashed line disappears, but regen doesn't move up the tap all the way to 60 kW. Thankfully, at this level, the difference in regen level is small, but noticeable (to me at least). Perhaps that is what is going on with your car if it is not a "charging close to 100%" thing.
