Pivot Table question

Hi Team,

We have tried to put pivot table with data in Excel. When trying to do pivot with new sheet, the Pivot Table Fields missing drag and filter fields. So, we have checked whether the "Field List "button disabled but No. Its in enabled status. So, we have tried and checked after clear re-installation of Office Package by run Click to run file. Please find below attached screenshot and assist further to get sort. We have checked the Ribbon column also, everything is good.
