Change Instances of "Classifieds" and "Ads"


I would like to change every instance of "classified" and "ad" to "audition" in within the front-end classified U-I. I changed everything in the post-type in custompress, and it is showing up properly on the admin dashboard (submit an audition instead of create new classified, etc.) but this is not translating over to the front-end.

Please help!

Thank you,
