'view/sheet set to print' from task sequence under shared laubchable parameters showing only 'ALL SHEETS'

Created Launchable Task sequence for one revit file,  so the users can select which sheet set to export, under Launchable parameters --> ‘Shared’ selected 'view/sheet set to print'. When run the task that parameter drop down shows only ‘'ALL SHEETS' so user cannot select anything.

Second issue is  If I click on the dots next to 'view/sheet set to print' --> ‘View Expression/SheetSet Selection’ I cannot select any of the check boxes, have to cancel and reopen to be able to select.
