good evening. to get your store categories on auctiva you need to go to the My Account Tab, Then Ebay Settings, Then Update store categories. That will add another scroll menu in the lister, just choose what category you want it in.
As far as the ones that you've already listed, your going to have to go and revise thru ebay.
Go to My Ebay
Active Listings
Select the items you want to revise, then click edit
The next selection is for info you want to revise, click on Item Details Store Categories, make sure nothing else is marked. Click on edit individual listings, (unless you want them to all go to the same category, then select Bulk) the next screen is where you select which category you want.
Hope I didn't confuse you more.
