Incremental Sync value is always true under Ranger Audit (Usersync)

Disabled the Incremental Sync in the Usersync configs but the Ranger UI -> Audit -> Usersync -> Sync Details shows the Incremental Sync value as always true. 

I could see the configs as - 

[root@c3245-node2 conf]# cat ranger-ugsync-site.xml | grep -a2 delta
  </property>
  <property>
    <name>ranger.usersync.ldap.deltasync</name>
    <value>false</value>
  </property>
