After upgrading to OMIVV 5.3.1 from 5.2, vCenter still shows v5.2 in OMIVV UI

I used the online upgrade option to update my 5.2 OMIVV (licensed) appliance.  While slow and with minimal status messages (annoying), it did complete and I'm able to login to the updated appliance Admin Console.  I was able to refresh the certificate and the vCenter (v7.0.2.00500) Client Plugins shows the matching version (OpenManage Integration for VMware vCenter 5.3.1.2505) as installed and enabled.

But when I pull up the OMIVV UI in vCenter, I still see it as version (OpenManage™ Integration for VMware vCenter (OMIVV) Version 5.2.0.2287) under Settings\About.  It seems to be fully functional, but I'm concerned that the UI is displaying a version different than the plugin.  Is this a bug?  Did the developers forget to update the About screen?

I did attempt to de-register and then reregister with vCenter and vLCM which worked without error, but the old version display remains.  How can I resolve this or should I ignore?

I have not attempted to reboot vCenter yet?  Perhaps that is what I need to do?
