A change was recently made (by me) to have it only show plugins on profile pages that the user is actually listed as a contributor for. This change is to prevent plugins from continuing to show up on users when the plugin changes hands to a new author.
In your plugins, you have the Contributors line in the readme.txt as "TC.K". This is incorrect, the contributors should be your username that you use to login here on WordPress.org. In your case, that would be "WP_Dummy".
When you use the proper username there, then your profile and gravatar and such will automatically be pulled correctly for the "Contributors" section on the plugin's listing screen, and the plugins will then show up in your profile.
All listed contributors to a plugin will get the plugin listed on their profile pages. But the listing is dependent on having the correct information in the readme.txt.
