I see what happened now. Heroic items where showing up in the Comparisons pane so I apparently removed the check mark from the "Other" option in the filters pull-down and once that was done EVERYTHING
disappeared. Consequently adding that check mark back in restored the list of equipment options.
That issue is resolved but I am still faced with a related issue. How do I remove those Heroic ICC/ToC items from the comparisons list? I have the check marks removed from Heroic in those respective dungeons but the Heroic items are still showing
up in the list. Should I create a custom filter to accomplish this instead of filtering them from the Comparisons pane?
