Just wondering if anyone could explain if I'm doing something wrong?

I'm playing Starters Orders Touch and have been trying to enter my 2yo horses into the 2yo auction, but whenever I put them up for auction, they just get put into the next weekly auction.
I have tried entering them in advance if the next 2yo date and also waiting until the exact date of a 2yo auction, but still find the same thing.
Am I doing something wrong?

I don't want to just enter them into the weekly as it is my understanding that they will be sold for a much lower price than a specific 2yo auction.

Thanks in advance!
