Two review buttons in product view and wrong positioning in product description

new

I am using the free version 1.3.0 and I have noticed that “Reviews” appears twice in the product view. Once in block letters, as intended by the theme, and once written normally. The second link does not lead anywhere and does not open another window.

I can't find the corresponding code in any file to remove the second, highlighted link.

When I click on the “Reviews” menu item written in block letters, a separate window opens and a second button appears under the existing “Write your first review!” button. Both buttons open the window for writing a review.

When I hover over the buttons, they suddenly turn black. I would like to change this.

In addition, the item “Rating: Write your first rating” has been moved to the right-hand side of the item description. This looks somehow strange.

Does anyone know these problems and have a solution? Or can someone help me with this?

Thanks!
