Ignoring one file, ignores all filetypes

Hello, I have installed teracopy 3.9.2 I have added a big folder with a large number of files in the source directory but I want to selectively ignore a few files and folders. But when I click on menu --> ignore --> ignoring selected file, it selects all the files with the same extension. I do not want that. I only want to select one folder/file to ignore. How can I do it in teracopy ? Thank you
