When you have a percent column and change the layout to “Flat form”, it does not calculate the perctanges well.
For example (i’ve seen this fiddle in the forum) if you enter here and change to “Flat Form”, show 1% in all the rows, which does not sum 100%

The flat form shows the raw data without any aggregations applied, just the same way it was specified in the data source. The percentages added next to the values in the example you shared should not be displayed. This issue was fixed and the latest version of Flexmonster works correctly. You are welcome to check it in our demo: https://www.flexmonster.com/demos/pivot-table-js/.
Please let me know if you have any other questions.
