After clicking, it opens a new window, which should not happen.

I only removed the command:

from the page, and since then it opens a new window, which shouldn't be the case.
Even after I added the command back, the problem persists.

The same thing happens when I re-enter the link; the error persists.

On other pages, the above command is not entered and it simply jumps to the page.
