Mappedname is being reused by another control

Hello,

 

I'm a newbie to the TestComplete tool.  I'm evaluating it for some automated testing.

I was recording the clicking of this link named "Documents".  You can see it being highlighted in recording mode.

In the keyword test item, I open the On-screen action and I see that the object mapped name is NameMapping.Sys.browser.pageUnderiterPortal.linkSubmission.

But when I clicked on "Highlight" button it shows me another control on the tested screen, where the name William is highlighted.

Is there a way I can update the mappedname of the object that I want to click i.e. "Documents"?
