Category issue.... (ver 2.08)

I have a cetegory named “Boots”.

I have sub-categories by Brands. In the sub categories I have all the products listed by brand. All is fine

Now… I copied the rows in my spreadsheet and added them to the main “Boots” category (so they would show up in both the “Boots” category, and also the sub-categories). Worked fine and are all are in the Boots category, But dissapeared from the sub-categories.! Can anyone explain why this happened? Thanks.

Will only work in one or the other unless you add it as a secondary category.
