Help needed on Microsoft PowerPoint 2012

I need to correct a large messed up Presentation file.   The previous owner manually inserted date on each slide!   I want the date updated automatic.  Like usual, I used the following steps but it didn’t work for me this time. 

In Normal view-slides, Click Insert -> Header&Footer->-Slide->Date and time.  Then click either “Update automatically” or “Fixed”.   Finally click “Apply to All” or “Apply”.  There are no changes on the slides. 

I can insert “Slide number” and “Footer”.   After clicking “Slide number” or “Footer”, there is a subtle change (lines become darker) in the small “Preview” square.  However by clicking “Date and time”, no changes in the Preview.  

I cleaned up the dozens of Slide Masters, then tried to Insert Date and time on the Slide Mater, nothing happened either.  Checked the internet too, but didn’t get any answer.

Please help!!  Thanks!
