Yes, I agree and just removed my answer since it doesn't actually resolve the issue. After looking at the results for that user I came to the conclusion that it is an aggregate value for each matrix slot meaning it combines all finds for all 3 countries to give a total. Using the link provided below the D/T matrix grid, I ran their screen name for each separate country and it does only show the caches needed in that country but doesn't show a way to separate out the matrices.
To my knowledge, I don't know of a way to get a separate matrix showing only US or Croatia, or Poland. LOL, I was a bit too quick with the Return button to provide an answer and didn't research it more thoroughly. We all make mistakes.
