Purchase Orders and Size Variants not importing correctly into Woocommerce

hi, we purchased your plugin 7 months ago but never used it until last week, sadly our support had expired and you did not communicate with us, so we had to purchase the software for a second time

hopefully you can help with our issues as the plugin is not working correctly

We are unable to download Purchase Orders, actually downloads 6 months worth, but we have 5 years of orders, also will not update new orders

Question 2 which is also a nightmare
the software is not creating variants actually it is creatng but it is not working and woocommcerce can not display the size variants.

Please help
