In case the categories' descriptions aren't correctly copied by the Tweakwise app, these descriptions need to be edited in the feed. It's not possible to do this within the Tweakwise app.

In Magento 1, you can do this in the module Catalog > Categories > Manage categories. Use the Name field to give the category a fitting name.

 

In Magento 2, this is done in the module Catalog > Categories. Use the Category name field to name a category.
