Oleg, I can't reproduce this in my local environment, but I can tell you here's how the gateway feature works:
1 - If you modify a network interface where the gateway is currently set, it gets unset (so we can apply a new one)
or if it's a DHCP interface, we also unset gateway manually.
However, if you have eth1 with a gateway, then configure eth0 gateway, eth1's gateway stays. You must unset eth1's gateway before eth0's gateway becomes the default. The highest interface # wins in this case.
2 - we run l23network in Puppet to apply config changes. This ultimately sets the new gateway.
A new default gateway is left as None if the new config can't ping that gateway. That leads me to think that it's your network.

I need you to provide logs and if possible, access to your env to see this in action. There are logs in /var/log/puppet and /var/log/fuelmenu.log to inspect.
