The time tracking report (billing_page.php) displays the project name as part of the summary of an issue if "All Projects" is selected.
It seems this is not what you expect.
If so, please explain step by step (and/or add a screen shot) where you would like to see the project name.

andrex,

You did not provide any feedback; I am therefore resolving this issue as "no change required".

Feel free to reopen the issue at a later time and provide the requested information.
