Thanks for providing the screenshot. If you will click the "Other search terms" question mark button in the AdWords UI, these are search terms that you didn't get any clicks within the last 30 days. You may also refer to this post from the AdWords Community Forum which discusses more in detail the "Other search terms".If you will check the Search Query Performance Report, all attributes, segments and metrics do not support zero impressions (Supports Zero Impressions = False). Therefore, the "Other search terms" with no clicks is not supported in this report type in the AdWords API. I believe that AdWords UI will only show you the total "Other search terms" statistics, but will not show you the breakdown of the "Other search terms" themselves.
