Recently upgraded a Splunk Universal forwarder from 6.1.2 to 6.2.2, but why is S.o.S - Splunk on Splunk still showing the UF version as 6.1.2?

We have upgraded a Splunk universal forwarder from Splunk 6.1.2 to 6.2.2 a couple of days back. I checked the version in the forwarder after upgrading, using the `./splunk version` command and it showed "Splunk Universal Forwarder 6.2.2 (build 255606)", but the S.o.S - Splunk on Splunk app on the search head still shows the Universal Forwarder version as 6.1.2 under deployment Status> Deployment Topology. I checked the splunk_instances_info.csv lookup table for hints and it too has the UF version listed as 6.1.2. The Search head itself is running Splunk 6.2.2 (if that matters). I have restarted the Search head a couple of times, but it's not picking up the correct Splunk UF version. Can anyone help? Thanks, Saikat
