That's what seems to be going on. Should I leave them alone or increase the spread? Right now its stock at .698v/.198v. Its seems to be more frequent w cooler MAT/IAT temps.
Maybe run less Prop Gain?

I've seen the same thing. The issue, in my case, was that the CTS was warm enough to go Closed Loop (~47C), but it wouldn't enter learn mode until even hotter. Finally determined that there was still a bit of enrichment occurring up to 68C. The learn mode only enables if commanded lambda = 1 (14.7), ie no enrichment.
Not sure if that will help, but you might look at it, and zero the OL enrichment above 56C or so.
