Hi there, 

Thanks for joining the QuickBooks Community. It's important you're able to edit your customer so you can get back to doing what you enjoy the most. Rest assured, I'll be happy to assist so you're on the right track. 

Based on what you've shared above, I recommend double-checking to make sure the edits you're making such as the name, doesn't already exist on the account. You can check this by clicking on Sales > Customers and review the list of your customers to make sure there isn't a duplicate. In case this is a browser-display issue, I recommend clearing cache and cookies.  Clearing cache and cookies helps with fixing most browser issues. You can do this by following the steps in this article: Clear Cache and Cookies. If you're still having issues after verifying the info above, I recommend contacting our support team so they can take a closer look at the issue.
