markets keep disappearing from my markets

Hi, when I load up the day's races that I want to run, I can see them all on my market tab.
However, as each race passes, I noticed that they get removed from the my market tab.
Is there a way to keep all the races I've selected as I want to be able to click through them at end of day to see the profit/loss on each race?

Hi
untick: settings > general options > delete settled events automatically

Thanks Mark. I should have worked that out for myself!
