Mysql Cluster Problem Field Autoincrement (no replies)

Hi

We've one problem with replication field autoincrement (Mysql 5.6).
Our configuration have one replication circular between two nodes.

Node 1:
auto_increment_increment=2
auto_increment_offset=1

Node 2:
auto_increment_increment=2
auto_increment_offset=2

With this configuration we solve problems of duplicated key, but we've gaps in certain cases.
Example:
insert in node 1. Id: 1
insert in node 1. Id: 3
insert in node 1. Id: 5
insert in node 2. Id: 6

After of each replication the system update the autoincrement of item in every node and we've gaps.
Is it correct? Exists some way of solving it?

Thanks
