The Selector executes its child nodes in order from highest to lowest priority (left to right). It will return Success as soon as any child returns Success. It will return Failure if all children return in Failure.
This means that when a child node return Success (as in your example) the rest of the child nodes will not execute.
If you want to execute all child nodes you will probably need to use a “Sequencer” node, which is kind of the reverse of a “Selector”. The Sequencer executes its child nodes in order from highest to lowest priority (left to right). It will return Failure as soon as any child returns Failure. It will return Success if all children return Success.
