"Limit list to selected items" exposed filter returns name of workflow.

Issue:
Please excuse if this has been addressed before. It seems like an issue which *must* have been previously addressed, although my quick search did not find this to be a duplicate issue.

I have a View which exposes a filter that allows admins to find nodes which are in select workflow states. The View is functioning properly and returning the correct results. However, it is displaying the (unselectable) Workflow names in the exposed filter drop-down.

Is there a way to expose the workflow state (in my case "QA Approval" and "Marketing Approval") without displaying the names of the Workflows ("Devices Workflow" and "Publish Workflow")?

Thank you!
