[Plugin: Woocommerce, WPAllimport]Variable product with more than 2 attributes.

Just as an example:

Variations

OD – ID – Quality
10 – 2 – L
10 – 4 – J
10 – 2 – J
10 – 4 – L
5 – 1 – L
5 – 3 – J
5 – 1.5 – L
5 – 0.6 – J

All the three above represent Attributes(OD – ID – Quality).

All the above are imported into the back-end correctly. Each combination showing.

At the front-end, when I select 10 in the OD attribute, the ID attribute still shows 1, 3, 1.5, 0.6. While it should only show 2 and 4.

I am sure its an easy fix but I have tried everything.

It is working properly on one of our other sites.

Thanks
