Conditionnal formating lost in Pivot table

[BenBBO]

Hello,

I've been trying to create an Excel Pivot Table based on a Flat List. It's working great, however in one of my cells, I've declared a conditionnal formatting to display a bar based on the value of the cell.

When my file is generated, the conditionnal formatting is not kept :

Expected result :

The template file used : Template

The rendered file : Rendered file
