Import into the wrong categories

When trying to import into predefined categories, products go into the wrong categories.

If the structure is:
product category > Towels > Towels

Products instead go into Accessories > Towels

This is even if a sample product is put in manually into
product category > Towels > Towels
The sample product is then exported and the category path is then put into the new CSV , in exactly the same way, however after the import again they are in the wrong category.

Also when one product is in two separate categories this does not show in the exported file.

I have figured this out, the best way to do this is, is rather than use column names, column ids should be used.
These can be found in category explorer.

e.g. 2,230,229 is Product Categories > Trousers & Jogpants > Mens Trousers And Jog Pants
If you want your products to appear in root categories remember to add the relevant column names.

This is a good piece of software
