The program shares a set of report styles to use for all tournaments. Each report that uses the same style number will appear the same, whether used in the same or different tournament.
A problem can occur, when changing a style, say #3 to appear as needed. If another report all of a sudden changes in appearance, it could be using this same style number.
The solution is to make sure that you use a different style for reports that need to be unique among tournaments. The program has several styles for use and modification.
