Hey Josephio,
Have you wired the enum up to the connector pane in LabVIEW as an input? TestStand will not recognize the enum control from your VI (or any other controls or indicators, for that matter) until you wire them to the LabVIEW connector pane.
Are you seeing the enum at all in TestStand's specify module window? Is it showing up as an input, however the dropdown window doesn't appear? Please post a screenshot if the above advice doesn't help you and I'd be happy to assist you further from here.
