All products out of stock after sync

After synchronizing the products, all of them are now out of stock and the message “The selected shipping method of this product is no longer available” appears on each product in the Dokan dashboard. Also, in “Shipping info to calculate price when syncing products” it appears as “Not available.”

I went to the ALD settings and, in the “Product Sync” tab, I changed the option “If selected shipping method is no longer available” to “Do nothing”. So I re-imported some products to return them to the correct state, but after syncing again, the products returned to the out-of-stock state. What could be wrong?

Changing the subject, when clicking the reimport button, wouldn’t it be possible to have a button on that screen to populate the title, categories, tags and description fields with the values that are in the published product?
