I cannot organize my bookmarks

When attempting to organize my bookmarks, it shows me three random pages which are not actually bookmarks and does not allow me to make any changes (deleting them, showing my bookmarks and folders and actually allowing me to organize them). The sidebar only shows the 'all bookmarks' tab. All of the options under the tab including 'new bookmark...', 'new folder...', and 'delete' are greyed out and not available. I can still create new bookmarks in the bookmarks menu or toolbar, but cannot change anything I have already done.

I tried starting in safe mode and my bookmarks and theme still remained - is that normal? Also tried deleting all of my bookmarks while starting in safe mode - succeeded in doing that, but the three random non-bookmarks still remain and cannot be deleted.
