Page Jump from Menu to another page section

Is there a way to get a menu item to link to a section on another page?
I have found this information below:

There are two steps. First you insert an anchor in your webpage:
<h2>Reviews</h2>
Then in Appearance > Menus, in the Custom Links box you put in the URL plus a pound sign plus the fragment name:
http://www.casafuturatech.com/smalltalk/#smalltalk-reviews
Then you can put the menu item anywhere in your menus.

After following the instructions, when I click on the customized menu label, it jump to that section of the page and then pops to the middle of the page.

Can someone please tell me how to get this to work properly. I need to get this to function for quite a few things on my website.

I am currently using the Cacoon Theme made by MetCreative if that makes a difference.
