values Bug

Hello,

I have a Bo (4.2 sp7) report which goes back to the following data: 13 and 40 :

but if I filter in the column on the value Paris=> the 13 and 40 disparity => null.

the exact values in the DB is null.

why the report goes up values when there is none in the Bdd. and when I filter => the good values go up.

Thanks in advance.
