Revert page back to original state

Summary:

A customization was made to remove the attachments section of a page, but it now needs to be reverted. The documentation was not kept, so I'm trying to figure out a way to change it back to it's original/delivered state. I've tried the reset task flow option in Page Composer, but that does not appear to be working. Specifically, the area (or dropBox, as titled in Page Composer) is where you would actually add an attachment in the Comments section of the Resignation flow. It seems to be flowing into other areas, such as adding an Absence. Please see below.
