Only products can be imported, import categories have no response

1. The category import was unsuccessful, and there was no response for a long time.
I see this error in the system status, /wp-content/cache/import-shopify-to-woocommerce/ writable or define a custom VI_S2W_IMPORT_SHOPIFY_TO_WOOCOMMERCE_CACHE. New folder /import-shopify-to-woocommerce/ and set 755 permissions, What do I need to do to ask for help?
2. I use the Perfect WooCommerce Brands tool as a brand in woocommerce, but this software says that the Metadata field is not used, I see vendor field or metadata field under shopify, how can I use this supplier to transfer to woocommerce to our Perfect WooCommerce Brands brand , thank you for your support and reply.
