Either use the firewall-cmd or disable firewalld and install (and enable) iptables.service and ip6table.service.
Firewalld will remove any entry that is not inside it's configuration.

I use iptable-save command

That doesn't save the rules, it only prints them. To save the rules you need to run service iptables save

[MartinR]

Or as the man page says:

Use I/O-redirection provided by your shell to write to a file.

You can do that but service iptables save makes a backup copy of the old file for you first and probably does other stuff behind the scenes.
