Under 21 Archers

On adding a new 20 yr old member the software flags that they cannot be junior and must be set as senior despite U21 being regarded as junior for competition purposes.

The software treats the legal status of a person differently from their age group.  The Junior flag is intended to highlight under 18s who are not legally adults and therefore subject to enhanced safeguarding etc.  This is different from their age group, so a person can be an adult and be in the U21 age group and qualify for junior competitions on the basis of age group.
