Using Food Marble 2 - Having issues - Numbers were near zero all day and then spiked out of no where

I've been battling SIBO-M for months. I thought by making the SIBO yogurt and taking some digestive enzymes, I was on the road to recovery since the pain and bloating has gone down quite a bit.

This morning, when I woke up, I was at 0.03, no methane. After breakfast, black coffee / almond milk and two eggs with salt, 0.04, no methane. Before lunch 0.04, no methane. After lunch, half a cup of SIBO yogurt, 0.04. no methane. 5pm, 0.08, no methane.

7pm, 9.2 - H-4.8 / M -8.6.

After dinner, green beans / small piece of steak - 7.9 - H-3.1 / M-6.0

I do not know what spiked it, as I was not eating anything. I have a little bloating, but no pain. Anyone have some ideas?
