      Expected : 'CreateDeliveries' last element is updated from NOT STARTED to ENDED.

      Actual : 'CreateDeliveries' firstelement is updated from NOT STARTED to ENDED.

Actual : 'CreateDeliveries' firstelement is updated from NOT STARTED to ENDED.

      I have an array of items, and I want to update the one with a name of 'CreateDeliveries' and a state of 'NOT STARTED'.

      The problem is this just updates the first element in the array, not the one that matches (i.e. the last element).
