Stock Not Updated from Wp-Lister

Hi, im using WP Lister by WP Lab, when a product is sold on ebay, the stock levels in Woocommerce arent updated. In the WP Lister plugin, it shows that it has updated stock level, but it doesn’t change. Im guessing there is some sue case here not accounted for, is there any suggestions on what I can look into to resolve it?

Thank you! ??
