Your site was down for maintenance a few weeks ago. Ever since then, I've been receiving emails that state, "Dear eForms user, The following task is waiting in your Applicant Tracking Enterprise eForms Pending Items queue. Document Title: Request Post Job" followed by a link: "Please log in to view the document." The documents are always blank. These emails come at 2 and 3 a.m. ??
You should be able to delete the blank documents by navigating to eForms > Document Search > find the document and check it > select an action > delete.
I have attached a screenshot below to provide a better understanding.
