It looks like the URL are being generated correctly. One is pointing to a specific review, the other is pointing to the review listing page for a product. You will want to update your website's Zen Cart templates for "reviews". Specifically the one used to list all reviews for a specific product.
One Review Display: "tpl_product_reviews_info_default.php" URL: ".../Review?reviews_id=1"
Review Listing Display: "tpl_reviews_default.php" URL: ".../Reviews"
If you need help, I would recommend asking in a new thread, or contacting the person who created the templates used by your Zen Cart theme.
You can also edit the product info template or the sidebox template to make the link the same if desired.
