The create template dialog only allows entry of the code path, but not the script to use by default. At the moment it appears to pick a random executable for the dir you specify. The only way I can see to fix this is to edit the manifest file after template creation.
Steps to recreate:
New template
Enter a code path
Enter a name
Hit save
New template is now shown with a job dialog on the right with a Script Name that was somehow chosen and is not changeable.
Thanks,
