That's the usual situation. Rule 10 sets maximum distance limits for different ages of runners eg Under 14s (ie those aged 12 and 13 on Jan. 1st in the current year) must not run in races longer than 5km.

However the "Rules for Competition" do not actually state the age groupings as such that an individual race organiser must use for his junior races. Whatever the groupings, the organiser will not break the Rules as long as the race distances are set such that the youngest runner in any race does not exceed the maximum distance allowed (as defined by the runner's age on Jan. 1st).
