Cannot edit the application title

Hi,

I have a NETWORK apps to renumber nodes - script lines are copied below (attachment #1).

It ran successfully, but every time I want to edit the Title (right click execution box, Set Title), an Application Manager warning says:
"The Program name in the script (PILOT) does not match the program name in the Application (NETWORK), for the script file ...\...S",
then the written script is gone, empty, just few lines left (attachment #2).

I've tried created a new one, successfully ran, but the same error message above shown when trying to edit the title.

Thank you.
