Visual header missing on just one table on Power BI Service

Hi, 

I have a situation where visual headers are visible for all visuals in Power BI desktop. 'Hide the visual header in the reading view' is also unchecked. 

When I open my report on Power BI Service, all visual headers can be viewed, but on one table. I need it in order to export selected data from that table in excel or csv from Power BI Service. 

How can I fix this problem? 

Thnx!
