JQL query returns wrong list of results

[Mouna Hammoudi]

I am using this JQL query to return the number of issues with issue age<=15 

filter = X and (Severity = 2-High or priority = 2-High ) and ("Issue Age" <= 15)

The problem is that this query returns to me issues that are also greater than 15. I don't understand why. Anyone has an idea?

Here is a picture of the results returned. This should not be possible since there is an AND clause.

Hi Mouna,

What type of field is "issue age" and how is it being set?

Also, if you could update the query to show where "Issue Age" >= 15 and then show the Issue Age of those issues, it might help determine how the query is working.
