File Names Saving with a question mark

Can't seem to figure out why all of my audio files are saving with a question mark at the end. For instance, the file might be something like, Hello_01_Example_02 and I'll save it as a wav file, and it will save it as Hello_01_Example_02?.wav. Then I have to go in to every one and delete the question mark, since the files have to be exactly as written. I've tried uninstalling Audition and re-installing, and it's still doing it. I'm working on a Macbook Air. Thanks in advance.
