Deleted pages showing up under Broken Links, but no links ever went to/from them

Tech

• RoboHelp 10 (project upgraded from RH7, 8, and 9 over the years)
• Windows 7
• Connected to a VSS repository.

Issue

The title describes what's happening, and I want to to know how to clear the Broken Links list of these links.

Here's what I did

1. Through the TOC sidebar, I added a page. (right click > New > Page).
2. Through the New TOC pop-up, I added a New Topic.
3. After adding the new topic, it showed up on both the project view and the TOC, as it should.
4. I wrote a bit in the file:
   1. I created multiple files, some using templates and user-defined variables, others  without anything more than your standard, blank page.
   2. There were no inbound (that I'm aware of) or outbound links. 
5. I went ahead and deleted both the TOC entry and the Project View entry.

Here's what happened

1. The file shows up in the Broken Links list.
2. When I vew its properties, it says that it has no references.
3. Clicking "Edit" does nothing.
4. The issue happened with mutliple test pages, none of which linked to anything.

History

• I inherited this file from another writer.
• Basically, I'm trying to figure out what they did or didn't do with this project.
• Right now, there are literaly hundreds of broken links, broken images, and I'm pretty sure I saw a monster hiding in the code.

TIA.
