@seanwes the next thing would be to temporarily reset Alfred's preferences to see if it's a misconfiguration or corruption.
Quit Alfred then open Finder to ~/Library/Application Support/Alfred/. Move Alfred.alfredpreferences and prefs.json temporarily to another folder (e.g. your desktop) and then restart Alfred.
