This is not a netfilter bug.

I just tried it myself:
Even though the control connection was made to 134.109.132.107, the FTP server
used 134.109.132.117 as source address for the data connection.

So you can hardly blame netfilter for this.

If you open the control connection to 134.109.132.117, everything works as expected.
