Tutorial fixes so marker can point to the "Add to existing" label

[IanMayo]

I'm going to change the tutorial, so that we guide the user to add the data to the existing map page.

But, I can't get the tip to point to the "Add to existing" label.

Could you investigate this, please? I may be missing a trick. Or (sadly) we may need some kind of code change.

I had the same issue before, that's why I went with the fast route of adding a new window, I am goign to check why the arrow its no pointing to the correct location.
