As you will see from the screenshot attached there is a clear discrepancy between the number of impressions and the lack thereof clicks, thus no CTR data. I know WMT dont give you the full amount of data but this is giving me zero clicks for brand related terms.Ive just started with this company so I dont know if it was always like this.

You can troubleshoot this by comparing GWT report with your Audience -> All Traffic -> Channels report. If your organic traffic didn't change dramatically during the time in questions then its a GWT issue.
