MS Word - words get cut in half at the end of line

I am doing English editing of a Word document written in Korean and then translated by someone. I am using MS Word 2011 for Mac. I have to edit about 60 of these documents, each is about four pages.

I edited about eight of them without any problems of formatting.

Then with the last four of them, I noticed that the words at the end of the line would get cut in half with one half of the word appearing at the end of one line, and the second half of the word appearing at the beginning of the next line.

I don't know how to fix this.

The documents have macro with them. Could that be the problem? Before, I was asked whether I wanted to turn on macros or not, and I chose "No" initially, and then I switched to "Yes". Now even though I went into preferences and chose "Warn me before opening macros", the documents open without this opening message.

I don't know what to do. I know Hangeul (Korean) is written so that it doesn't matter whether words get chopped in half and the original document was written on MS Word for Koreans (and has Korean fonts and things like that).

But the person who sent me the original document is not available and besides can't speak English so I can't ask her about this.

It might not have anything to do with macros. I remember vaguely a while ago I had the same problem and I fixed it using some simple measure but I can't remember what I did.

I browsed the web looking for solutions but have not found any.
