For some strange reason, the tracking number will not appear in the My account page.

I have done this:

Change #1: (highly recommended - Making this change will allow your customer to track packages from the "My account" Page.)
define('FILENAME_ACCOUNT_HISTORY_INFO', 'account_history_info'); to
define('FILENAME_ACCOUNT_HISTORY_INFO', 'tracker');

Still it wont show the tracking numbers in my account page.

Here is my website, and you can make a test account if needed.

using TY tracker version 2.3a

and using Zencart latest 1.3.9b

Any ideas what may be the issue? thank you.
