Workflow - Create task step for custom object 2

I have developed a workflow that has a step to generate a task when the workflow condition is met.  The task is for Custom Object 2.  I've verified the workflow condition is being met, and the task is generated, however, it does not associate the task with the custom object 2 record.  Desire is to show these activities in the Open Activities or Closed Activities Related Info tab of the Custom Object 2 record.   In a different environment we do this same thing with Custom Object 1 and it works just fine.  Is this an SR or am I missing
