wrong product names

[Oliver2003]

Hello, I have a lot of products with same sizes available, so I am just copying products, updating product names, prices and pictures etc...
But with some product I copy the product and change name, but eshop is still showing the old product name (1st picture). In my Shopify editor everything looks fine also URL is fine (2nd picture).
can someone help me how to synchronize it? 

I tried different device, anonymous window, nothing worked.

  

Thanks
