Any help regarding this will be appreciated.

I am not very sure about your case but then I had faced the same, actually they had disappeared after disabling security on the tablet but the I was able to get them back after enabling it again, if you want then you can set it to "Not secured" rather than disabling security and with this you won’t be losing the lock screen ring as well as the quicklaunch ring,first just check out if you are having the same case or not.
