Photoshop Actions - setup for automatically adding name of the file to the printed image in corner

Well not quite. I am using the script down below. I included this script in actions with other commands and it works very well if i play the actions in photoshop. Problem comes when i try use those actions which include this script in batch process from adobe bridge. When i start batch processing than with each image file i try to edit with those actions the preferences window comes up and than it wants from me to click through every step of add naming and positioning layers of things which the script is doing with recorded positioning movements.

Do you know any fix which could help me sort this out? I can not work without batch processing.

Thank you.
