Ah OK, I thought that you set Sec->Live to true only in `setSectionLive()` but you manipulated that in EnqueueMaybeLDSA as well. Looks like we have too many callback functions in this function -- this file is organized that way because the callback functions were very simple. Now it's been growing organically and probably get to the point that we should just use the regular class-based abstraction. Let me do that first.
