If you go to TDAdmin > Users & Roles > Users, and open up Jennifer's account then go to Desktops, she legitimately has multiple desktops of the same name. I suspect this is because she had the custom desktop then someone also marked the desktop as linked and assigned it to her. You'd need to edit her account there in TDAdmin to remove the custom desktop(s). Or she can try to remove them herself from TDnext.
