Could you check in the settings if the 'Auto update data' option is checked?
Settings for Live Mode Overlays
Select number of links to display (or all) and the Gainers or Losers (or both) to display as overlays.
Exclude bottom (%)
Select to eliminate Gainers-Losers links with sparse data. Filter out the bottom percentage of link changes to view only the links with enough data to show relevant gains or losses. The percentage is computed based on the number of links on that page. For example, filtering out the bottom 10% of a list of 200 links would filter out the last 20 links.
Auto Update Data
Lets you decide whether the Analytics data shown in the interface should automatically update when a new period is computed, or not.
Auto Update Period
When checked, refreshes the web page with each new data retrieval so the links in the page can be more closely synced with the collected data.
