Failing to Upload Titles | WordPress.org

I had an existing BookVault account for selling direct via Shopify but then closed my Shopify store and used my existing website instead. The Woo Commerce plugin is installed Ok and so is the BookVault plugin and though both are connected, titles are shown as listed in my BV account but they aren’t there in my Woo Commerce products on my website.
Is there a fix here? Thanks!
