Fix a bug on a woocommerce website

Hi, We added a tag over the product card image, on the product list page showing that the product stock is bigger than zero. The tag called "hizli teslimat" which you can see on this example page; [login to view URL] You can see that the first product is tagged, but the second is not. This is correct. But we need to show the same tag in the product detail page. My last programmer added the code, but its not working correctly, you need to fix it; [login to view URL] for the other variant of this product, the stock = 0, so the tag should not be shown for example; [login to view URL] And the last problem is that you can click on the variations of the product and some have stocks, some have not. You can see how the information is changed on this product detail page. So when the information changes with clicking, the "hizli talimat" tag also need to be visible / hidden. I need you make the modifications on our test page, and tell me exactly what changes should i do, so i can modify the online website. Automatic bids for less then 3 minutes will be ignored. Please read carefully the specs and bid a exact price and deadline. I dont like to change the deadline and the price after discussing the details, because the project specs are really clear. I will give you FTP and wp-admin connection informations. txs.
