I believe I have found the problems with these races now and they have been set to re-run in the next calendar slot.
Our sincere apologies, we know why this happened and it was more of a fluke occurrence. 99.5% of the service was running normally when this happened, but 20-30 races did not run. The thousands of other races in the service had no issues and ran normally, which is why in affected leagues some tiers were fine while others could not enter.
