Image Processor works fine but gives a script alert, it also gave different output with same script




Image Processor takes the images, apply the action and succesfully save the files in the correct folder. But for some reason, it gives me a Script Alert saying "Sorry: I could not process the following files: <input image file names and paths>" as you could see from the pictures too. Is it something that I should worry about? I want to automatize my work but I don't want to risk any mistakes. Also, I ran the same script a couple times and once, only one file was saved when it had to save both of them, which was just unexpected for me. I did the same thing once again and both files were saved. I'm kind of confused, what should I do?
