since 12/12/16 the CTR for imports from Google Search Console are not cached correctly. Can you check?
Value for CTR is always 0
As this data is then also stored locally all saved data need to be updated since 12/12 also.

Ok change of issue: In the past the values for CTR were just "0".
Since today the value is "Can't be calculated, would require summing deduplicated values"
This has now been fixed.
