You add some new DOCL(Date of Click) or DOC(Date of Conversion) metric columns in your recurring report from the Report Templates, and it looks successful as you see all the newly added columns in the report settings preview. However, the exported report is missing the added columns and/or other columns such as Conversion Types and Conversions / Revenue columns with DOCL or DOC values.
This issue occurs because you can add both DOCL and DOC columns to the report in the report builder, but the platform does not support using both DOCL and DOC columns in the same report.
Here is an example situation: You see the DOCL view in the Keyword tab, go to the Report Templates without knowing that your view setting stays in DOCL, select a report which was previously made from DOC view, then add a Conversions / Revenue column to the report from DOCL metric columns.
Our Product team is actively working on the issue and we hope to have a fix soon. In the meantime, please follow the workaround in the next section.
