Is this a men-only league? If so, you will need to, in your league rules (Setup > Rules > General Rules tab) scroll down the first screen as there are more settings than can fit on the screen. There is a setting "Type of bowlers" and if it's a men's league, "Adult league - all men" instead of the default "Adult/Youth league". You don't say that your league is all men or mixed, or whether it is indeed mixed and you have a merged local association.
