Unable to delete a document showing up in the Recents Tab

I'm unable to delete a file which shows up in the Recents Tab on the welcome page in the iPad Acrobat app. When I click the 3 dots by the document name and select Delete file it says "Unable to delete" on a red tab at the bottom of the screen. This document strangely shows up only in recents and doesn't show up in and folder including "On My iPad". Appreciate any help with deleting this document.
