How to use just first 5 users from CSV fle containing 20 users in JMeter?

I've got a CSV file with login identifiers (there are 20 logins at all). I'd like to use just 5 of them while testing, but with repeating equals 10. So every of those 5 users will be log in to the system 10 times. How to do this?

I've done such configuration:
Thread Group: CSV Data Set Config:

The CSV file is like that:

login1
login2
login3
login4
...
login20

But while testing I see that not just first 5 users logs in to the system, but also login5, login6, etc.
Why JMeter uses more than 5 users (thread)?

Any ideas for fixing/improving my configuration?
