Closed Loop Disabled but still adding fuel?

I was doing a little touch up to my MAF table and I noticed in the scanner that the 02 sensors were still adding fuel even though they were disabled in the tune. Closed loop enable was set to 284 across the entire table, and LTFT are disabled. They didn't seem to add fuel the entire time, only in occasionally. Is there a reason for this??
You can see it mostly at the very end of the log when I pulled in my driveway and let it idle for a bit. But if you skim through the entire log, you can see spikes from the 02's out of no where and then the AFR goes rich. Just wondering if this is normal?

Yes fuel trims were reset. You would have to see the log. I don't know if it's adding fuel or what it's doing.
But you can see at the very beginning of the log, the O2's are silent and it idles at 15 afr. Then if you skip to the very end of the log, the O2's start creeping in and the afr goes to about 14.3...

I just looked at the log, I dont see the o2 adding anything? ?? The only thing I see is the 02's start switching, but they should be considering what your wide band is reading...
