Now, I close down RDSS and re-open RDSS. Now, things get funky with BL/BL:
7 and 3 switched tiers, and the Primary Factors of the contending horses now have some 6 and 7's, seemingly taking on the ordinals from the non-contenders.
The Rx also changes, although the horses ranked do not change order:
Next, I change the 1A, 2 and 5 back to contenders. Then, change them back to non-contenders.
This fixes the issue for now, at least until the next time I close out.
