I'm not building from source because the environment is windows and I
don't have a way (and knowledge ) configure all compile environment.
But thank you for the explanation I understand the problem, it's
probably that because labels with big numbers are converted to
scientific notation.
The round values are ok for visualization in the labels but not to use
in the class filter expressions.
I will waiting ... thx
