Contact lookup fields not syncing from CRM to reports

Contact lookup fields not syncing from CRM to reports

Hello, 

we use Zoho CRM Advanced analytics in Zoho Reports. 

We use the standard Contact lookup type field in Potentials in Zoho CRM, but this field does not sync to Zoho Reports, the column is not shown at all. I need that column to be synced. Is it a bug or a feature?

It is quite crutial.

Thanks, 

Vitek
