Hi there,
Short version: Requested matches counter is not in sync across the site - if you check the screenshots you will see what is happening.
Longer version:
Visit the home - 2 requested merges
Click on the requested merges and the title for that tab says (0) requested merges
Click on another tab on the same window (Matches for example) and the tab with requested merges now says (2)
Click back on the requested merges tab and you still have no merges (as above)
Hope the information and screenshots help
Chrome Version 46.0.2490.80 (64-bit) (Extensions: Google Plus, Toggl, LastPass,Zendesk, Pushbullet), on Fedora 22
