I am creating a new vault off of a demo vault i set up to show users how PDM will work in the future. The demo vault I can manually change revisions with the "Set Revision" option. In the new vault, I don't get that option to change a revision. I can bring up the set revision dialog box and everything populates fine but the new revision box. The only option in the drop down is the revision that the document is currently in. Normally I would see A-Z letters, this just just the letter the document is in. Any ideas?
