No Drainage Structures in cross sections


I've been able to process the nodes in plan and drainage section pattern lines. When I attempt to process the sections all seems to go well, but when I process to add the structures,all seems to go well until I never receive the dialog box to specify the stub there are no structures added then.

Not sure what to do, as I receive no errors.  Only thing I can think of is that we recently upgraded our MS office products to 2016 version.
