A fresh format and install didnt fix this. It optimized these 19, and then went on to optimize the other 180 or so on first boot like it should. Now it keeps with these. This is looking more and more like the xposed issue posted @ https://github.com/rovo89/Xposed/issues/142 only that was seemingly pinned on link2SD with no definitive answer. These are all baked in apps and services that it wouldnt/shouldnt be moving around though.
