The issue might be the method used to extract references from Google Scholar. References from Google Scholar can be exported directly into an Endnote library – no import filter is needed. If, however, you are extracting references from Google Books (concerning books and magazine articles) then you would need to use the corresponding Endnote filter (for Google Books). If you are experiencing problems in the latter situation (Google Books), then please provide further info.
