Not able to share performance document issue.

Summary:

The performance process flow is set up to have a first approval step with a rule that sends it to an HR Rep for approval. After the HR Rep approval there is supposed to be a step for employee acknowledgement. The document is getting pushed to that step after HR approval and I can see it is in ready status but I am not seeing anywhere to either share the document when logged in as a manager or acknowledge the document as the employee. What am I missing? The manager only has the option to view or print the document.
