Question: Can't understand the output

I wonder if someone would be kind enough to explain the output I am getting in the simple attached file. I understand the array that is being output - that is what I want. But why the 9 below it, and the pair 'true,true' near the bottom? -Thanks View 2292_IncrementGroup.mw on MapleNet or Download 2292_IncrementGroup.mw
