Found process(s) number should be greater

Hi,
I'm creating a new process monitor.
I set the monitor to look for processes.
  Interval Type: Greater than or equal to: 3
   In the test results, it returns 3 process found.
But after I apply it, I receive an email problem stating:
  Found process(es) number should be greater than 3 . Expression is 3
It appears "greater than or equal to" isn't working.

I change the value to 2 and it now works fine.
Please let me know if using 2 is correct.
Thanks.
