When I switched from split to 3 under, the same thing happened. Since you can control it by focusing on it, I guess you'll just have to focus on it for a while. In my recent tuneup with Rick, he noticed that I was consistently shooting a few inches high, and wanted me to raise my nock point to bring the POI down. Since my bow is perfectly tuned as it is, I'm reluctant to do that. Like you, if I focus, I can bring the POI down, and my expectation is that my brain will reprogram after a while, and it will become my new autopilot setting. Maybe that's the reason for my unexpected high shots this morning: my brain is in the middle of reprogramming itself. At least I hope so.
