Request a quote showing for all products when selected for only

Hi

I have added the plugin to our clients site and selected the request a quote button only to show for out of stock products, though it is showing for all products.

You may see the link to a product that is in stock and you will see the button is showing.

Please can you provide assistance on how to correct this.

The website is using the Astra theme if that does provide any known insight for theme conflicts.
