Filenames with Parenthesis will not save

[Toddfra]

The default filename has parenthesis in the in the title -- i.e. "(Special Edition)" . I think this is preventing me from creating a .mkv file. How can I change the filename or overcome this?

What operating system?

Generally speaking, MakeMKV will allow () in file names, and both Windows and Mac operating systems support them. I recently ripped "Legend of the Last Labrinth (subtitled).mkv", but that was manually entered, using the Advanced settings, to replace the default.
