Thank you for your response and sorry to sound thick.

In response:
1) So in EP4 the CSV export only offers v_categories_1 - this is installed on the new website. On the old website EP0 is used and exports a CSV with the headings v_categories_1, v_categories_2, v_categories_3 and so on up to 7.
2) Only English.
3) Just English
4) Shoes for instance below:
v_categories_name_1 v_categories_name_2
Shoes Size 6
Shoes Size 5
5) I've taken the latest version of EP4 for the new website. The old website uses just Easy Populate from several years ago.

Thanks, Rich
