Jobs are not getting assigned to labeled nodes. While digging into this, we discovered some cases where the node labels are not appearing on the node status page. When looking at the node config page, the labels do exist.

• Agent is configured as (slave-it0400-config.jpg)
• After saving the agent configration, assigned labels are not being showed on the slave status page (slave-it0400-status.jpg)

But labels are actually serialized in the agent `config.xml` (slave-it0400-configfile.xml)
