What are the applications? What is the directory structure? Is the
permission problem on a directory or a file? What user account owns
the application process? Is the app un-doing your manual permission
changes on existing files and directories, or just not granting read
permission to new objects?

If an application so chooses, it can set whatever permissions it wants
on newly created files. It may even have logic to alter the
permissions on existing files. You may not be able to control it from
the OS level.

Or, it could be as simple as setting (or changing) the umask in the
application startup script.
