GeoIP

Is anybody having success in using the GeoIP functionality? I am not and i find it quite frustrating.

What have i done:
1. created a country group within that group f.i. Romania:

2. created a Drop rule based on the country group:

3. Have been checking logs for a couple of weeks, today i saw that there wher entries in the log showing me that traffic was allowed originating from a Romanian IP:

And this is only one example, my log is filled with more similar ones.
Any thoughts on this? Is my thinking wrong, was my execution poor or are my expectations not right?
