Jmeter - Getting previous results in mail

I'm using Jmeter - it runs automatically every 4 hours (through crontab). I'm sending the results file (csv) in the mail at the end of the test. I always see the file of the previous test, not the current one (I can see by the hour).

the structure is this: one 'Test Plan' (I checked 'Run Thread Groups consecutively' and 'Run tearDown Thread Groups after shutdown of main threads), two 'Thread Groups' - which at the end of each I write results to csv file using 'View Results Tree', and at the end - 'TearDown Thread Group' that uses SMTP sampler to send the files created.

any help would be appreciated.
