Shape Report

[Toxicboumboum]

Hi everyone
I'm trying to do a shape report with the cost value that I calculated, until here everything it's working
but Sometimes  my shapereport mulitplies my values inside my report without any reasons
So for example I have some costs which are equals to 15.8625 or 8,8125€ and my excel report show: 158.625 or 88.125
Any idea of why?
