How to Capitalize Journal Names

I’ve got a problem with capitalizating journals’ names which the first letter of each word must be capital. When I import or write my references, I do consider this: I go to Edit and make the first letter of each word capital (from lower case to upper case). Then I make sure I’ve pushed the Save button. But when it is over and I come back to Word Bibligraphy  or Main Page of my EndNote, the changes are not applied.

I wish you can help me. Thank you in advance.

I suspect you have a “journal terms list” which has imported the titles and is being used to replace them.
