All I did was go to "Lock Screen Settings" and under the 1st Tab "Personalize your Lock Screen" by default it would be "Windows Spotlight" what I did was I changed it to "Picture" and that'll remove all the stuff, it'll just remain blank and just show the time alone. I didn't like this so I changed it back to "Windows Spotlight" and that seemed to sort out the problem.
Prior to doing this I had changed my time and date settings etc. and restarted but that did not help. So that's what I did and it worked.
