Hi @meltitbyae
That additional button seems to have got added due to some custom coding on your site. It could also be from the theme, especially if you are using a child theme.
In line with @auludag ‘s suggestion, even our recommendation is to temporarily switch your theme to Storefront to see if that makes that extra button disappear.
You can test it on a staging site using a plugin like WP Staging, without affecting the main site.
If that doesn’t help, then you may need to consider performing a full conflict test to try and narrow down to the potential plugin from which that button is coming. This will involve deactivating all plugins apart from WooCommerce apart from switching to a default WP theme like Twenty Twenty-One or Storefront. If the button disappears at that point, reactivate the theme and other plugins, one by one, all along checking if the button returns, to find the plugin that’s at the source of it. Here’s the conflict test guide for reference: https://docs.woocommerce.com/document/how-to-test-for-conflicts/
