I am using the $WARNINGS_NEW token in my email notifications but (most of the time?) its value does not match the one shown in the warning results page of the build.
Instead, the new $WARNINGS_NEW seems to be equal to $WARNINGS_COUNT.

For example:
I get a mail reporting 118 warnings in total and 118 new warnings.
When I open the warnings result page it shows 118 warnings in total and 0 new warnings (which is correct).

I remember that I already had mails where the values were not equal but I can't recognize any pattern and again, most of the time, the new warnings value is wrong.
