Editing the Schedule PDP, at the Page Details Web Part, inserted wrong Project Web App URL. Cannot access Project Schedule Pages.

Question

I need a help. The environment, SharePoint and Project Server 2013 and SQL Server 2012, running on Windows Server 2008. Editing Details Web Part in a Schedule PDP Page, saved invalid Project Web App URL. After that, can display the Project Information and Project
Details Pages from the projects accessed, and can display the Project site, too. But, when I access the Project Schedule Page, receive an error page, because of the invalid URL. The message is obvious: "There
is no Web named xxxxxxx". I´ve tried to find out how to correct this, but no success, because cannot open the Project Schedule page anymore.
I would like to know if there is some way to fix it without re-installing the system. Thanks for all. If somebody need more information, have log information and page display available.

Paul,
When I click Schedule after PWA Settings > Project Details Page, there comes the error.
I can download the Schedule Page. But I don't see where to change, because the wrong URL doesn't apper at the page. 
I'm sending below the page that I can download. The schedule.aspx.
