Claim/Close Action Buttons

How do we rename the Close and Claim buttons that were pushed to the Case Record view during the last update?  Outfitters are clicking Close, thinking this will just exit the case....We have many different statuses they need to choose from, so I need to either rename or remove that new Close button. I have reviewed the Action Button Documentation, but I do not see where to find the Claim and Close button to edit or remove. They do not show in my list of fields to select to configure in the Case module. I did not add these, the upgrade pushed them in. I am probably just missing something.
