Pivot table shows "Can't load all the data" when enable "Row Total"

Hello Joshua,

First of all Welcome to the QuickSight Community.!
Is your table too big ? how many Rows & Columns are we talking here ?
if the issue is with only Row Total I would suggest to raise a AWS support ticket and report the issue. This will help AWS team to gather and identify the exact cause of the issue.
To raise the ticket, please follow the below link -Creating support cases and case management - AWS Support

Hope this helps.
Cheers,
Deep
