CamTrackAR autofocus lock not working?

I'm using CamTrackAR on an ipad pro 4th gen (with LIDAR) and I'm finding the autofocus lock doesn't seem to be working. I've done a number of videos with it locked and I keep seeing refocus events happening during recordings.

At least, that's what I think they are....when I examine the track I see the "current focal length" go up from 29.8 to about 30.2 and back down again...the video clearly jumps and gets defocused briefly.

Haven't tried this with my iPhone X yet, maybe it's only the iPad that does it? In any case it's real annoying because it ruins shots, causing you to have to go back and reshoot quite a bit.
