Clarification of rules to say that a digit may repeat on an island but the killer cages will not repeat digits

To clarify the rules: all the digits on an island of size n with n>1 must sum to 5xn? But then there are multiple solutions…
Ah! So every island of size n with n>1 is a cage within only the given digit (size) may repeat. It works.
