Can’t import Coupon codes into shopify from Woocommerce

Hi There, i am trying to push the coupon codes into shopify, but it seems nearly impossible to push them, it shows that the woocommerce doesnt have code, but meanwhile we have around 6k codes (i also checked the requests via network) and in first requests it finds the coupon codes (check image: code-found-1.jpg) and then immediately another request shows that no code were found (check image : import-data-3.jpg) ,
and import-status.jpg shows the front-end how it shows.
