Keyword Ranking History Chart

The attached image shows the Keyword Ranking History with big downward spirals on Aug 27 and Sep 24th. Yet it's also showing up within the #10-#20 row.

What is the official technical reason for why it's in both places? My boss is asking and I'm blanking. Just that the URL was found in both spots?

There are two or more different URLs on the same website competing against each other for that search query. If you hover over them or scroll down you can see which of the URLs they are. Trouble is, since they are competing against each other, it may be harder to climb the ranks as Google is getting confused and doesn't know which one to rank.

Better to have one single URL with content optimised to target the search topic and keywords, as it relieves Google of having to make the choice and ultimately... screwing it up.
