Sonar i-Code CNES 2.0.2 plugin not consistent

Dear all,

I am using Sonarqube Community Edition Version 8.2 and I´m trying to analyse some projects with the fortran plugin Sonar i-Code CNES 2.0.2.

Unfortunately, after launching a couple of scan I have realised that the results are not consistent, I mean launching the same project several times the scan results are different, sometimes shows 120 major issues other times just 80 …

There are several rules which sometimes take them into account and others that they do not, even though is the same project.
Could you please assist me in figuring it out and have consistent results.
