Age Group
The two genders (e.g. Seniors women and seniors men) are two different age groups and don't have any connection besides the almost identical name. The name of the age group is generated during import by the provided name and the gender. This also leads to the unique path of an age group.
If "Do not print gender" is selected in the competition software, the gender is not added to the age group name and is therefore also not part of the path.
All age groups, including age groups of different import configurations, must have different names to prevent duplicate paths. With duplicate paths only one of the age groups can be selected from the event page and the other cannot be displayed.
It is therefore recommended to prevent duplicate names by adding a suffix: e.g. "Seniors Sprint"
This will probably be improved in a future version of Skate Results
Empty age groups can be hidden via a setting in the general options of an event.
