Shipping by zone does not assign the correct zone

Hi, while configuring the different zones in woocommerce to be used in the dokan, to make local deliveries in the city and each one with their postal codes.
ex: zones configured in woocommerce:
zona1 – 65050000 – Fee amount $ 10
zona2 – 65060000 – Fee amount $ 15
zona3 – 65070000 – Fee amount $ 20

During the tests, when the purchase was made, woocommerce calculated as if it were the value of the first zone.
ex:
zip code 65050000 – Fee amount $ 10
zip code 65060000 – Fee amount $ 10
zip code 65070000 – Fee amount $ 10
