Ok - Here is an update. I found that it has a basketful of entries for each Category and I have a pretty good list of categories.
Attached is an image showing what is happening in one category. There is an entry for each sort option which I understand where this is coming from (Sort Name, Sort Price Ascending, Sort Price Descending) what i don't understand are all the "rw=1" entries. And why they stack up like they do.
Is this an issue? I am assuming it is because there seems to be no real reason for it.
