The reason is that the .fac file was generated for the last cycle only, just as the .par file. Please disregard that file and replace it with the original.

Z12 was not supposed to generate a .fac file on re-training, but it did for some reason. This will be fixed in the next update. Z3 had the same problem. We'll change the behavior on that occasion so that [Train] also re-trains only.

- The fixed WFO cyles come from setting EndDate in the script to the date when the system was last fully trained.
