In some cases, you need to edit names of your Rate Groups. To do that you can do the following:
1. On the Left Hand menu, go to Rates and then Rate Groups. You'll list of created Rate Groups on the right-hand side of the page. Just find that rate group and click on Edit.
2. Next page, you may click on the field that says Name if you wish to change the name of the rate group, or change the invoice prefix or the codes. Click Save once done.
3. You will then see a confirmation message in blue at the top.
