Can you help me to understand \* MERGEFORMAT?

HELLO TO EVERYBODY!!! (^____^)



this is my first message and I need your help for one questions: =)

I'm not very expert of MS Word, but I'm writing a small book and I'm using a cross-reference ( I don't know how to call this tool) for picture, paragraph and chapters. I have also a index at the beginning of the book.





PROBLEM #1


Today, I discovered that a lot of my "cross-references" (for example, Fig. 5.45) if I show the "Code", looks like this:



[REF_Ref504939385_ \h \* MERGEFORMAT]


The "funny things is that, some backup ago, the same field was simple:


pREF_Ref504939385_ \h]


And, if I create a new cross-referencefor the same picture, the "code" has no " MERGEFORMAT" text...


So, why does Word add this code? For what? How?

I tried to search in Internet, but without luck :/


Can you explain me?


thank you! ^__^
