Keep AFL only on 1 sheet

Hey folks,

I downloaded an AFL which highlights different chart patterns (wedge, triangle etc) on a chart. When I drag and drop it on one sheet, it get's applied to sheet 9, 10 and onwards, till 18 (but not to all the sheets present).. If I remove it from any of them, it's removed from all of them. How can I change that?
