Constant lows after switching to minimed

I just switched to the Minimed 722 after using Animas for 4 years. My basal rates are exactly the same as when I switched from the Animas, but I have been having constant lows while fasting. Has anyone else experienced this? There is definitely something going on here.

I’m ready to decrease my basal rates significantly, but before I do that, it would be nice to find a possible explanation for this.

I attached a chart from today after lowering all of my basals by .1 units last night (from 31 units/day to 28 units/day). Over the course of that entire graphed period, I didn’t take any boluses. The spikes are where I corrected the lows.
