Like everything in PlotMaker, this is obsolete. In AC10, the info is in Project Info.
PlotMaker AutoText can display information about the project stored in the Layout Book Info. You can then use AutoText tags in title blocks to display the project name, address, etc.
Why is this important now? Because of the the new SK title block, multiple independent title blocks may be placed all over a project. With AutoText, you just need to enter the info in the layout book once and all the titles will be correct automatically.
The title block objects have been updated so you have the option of using the book info tags. And the defaults have been changed, making the book info quasi-mandatory.
To fill in the book info, in PM go to Book>Book Info... Here is the properly filled-in book info for the Stevens project:
Layout Book Info dialog.
Note the Project Name field: This forms the second line of the project name. The other fields should be self-explanatory.
Here's the Stevens title block with the AutoText options enabled:

And the interpreted text in PM:
