Comment (by westonruter):

 @kylejennings83 The reason why it is being called multiple times is that
 the validated/sanitized value is not cached for a given changeset setting
 value. If you output the `current_action()` (or even `debug_backtrace()`)
 in the error log for each instance, this should illuminate better the
 times the situation that this is being called.
