Hey there,

Were you by any chance using the beta version of Google AdWords? If so, please recheck your results using the link below (they should be identical):

Besides, you might have been using a proxy (or proxies) in Rank Tracker. If so, please disable them via 'Preferences -> Proxy Settings' and 'Preferences -> Search Safety Settings -> Proxy Rotation'. After that run your search for keyword suggestions once again.
