When I attempt to Export a Map (File --> Export Map) the Option drop down in the export page either has no options ("the [method] you selected has no options") or it just has one or two but NOT Export Multiple Pages as one PDF i.e. where I can select Pages 1-8 for instance, or the entire document. My only solution has been to Exit ArcMap and Open up again. Basically Export Map does not recognize that I have Data Driven Pages Activated.##
Any ideas? I'm ArcMap 10.6.1
