Hello All

This is my 1st post on this forum and also the 1st appearence here
I am on word 2007 and since a few days ago I have been noticing a strange thing on my word documents that I open up. (lacking the exact technical terms in my vocabulary) I see that the headers ,footers, template sections have changed to their 'raw skeleton' form

to make you understand what I mean here , I have attached some screenshots of my word documents. the encircled parts used to hold data like : author, date, topics, versions, page numbers etc. but now I only see the meta data sections and the value of the container is completely missing . However the content of the word document in itself is still intact and legible.
pl. see these screenshots links

I hope I was able to show my issue with the help of the attached screenshots.

could anyone assist me , why is this happening and which setting is coming into play here ?

Thanks in advance
