Attachment gone when removing item from database?

I went through some old Notion pages and noticed that, below one of my databases, there's a few pages that used to be items in said database. Each one had an attachment. Now that they're pages, those attachments are gone :O

My best guess is that they've been accidentally dragged & dropped out of the database, but I have no idea when so I can't restore an old version. I tried dragging the pages back to the database hoping that would once again reveal the attachments, but no luck.

Any suggestions on how to recover these files?
