Hi ArisMos
Not sure what is happening to you but I've just tested it on my side and it's working as expected.
But, please note that the product title has a blue colour but it never was editable. It's just a link that opens the product on a new tab.
Did you try to clear your browser's cache?
And might you check id you have any kind of JS errors (in red) in your browser's console, please?
Best Regards,
Salva.
