I know you've been in a tough spot here, @acctcontroller. I'm here to help you get past this situation.

A cache-related issue is likely causing the inability to edit custom report groups. If this is the case, you can perform some troubleshooting steps. You can use a private or incognito window to rule out cache problems in your browser. Here are the shortcut keys:

• For Mozilla Firefox browser: Ctrl + Shift + P
• For Google Chrome browser: Ctrl + Shift + N
• For Safari browser: Command + Shift + N

Next, log in to your QuickBooks Online (QBO) account and re-edit the custom report group. If it works, you can clear your browser's cache. This removes the webpage data that's causing the issue. If a private browser doesn't work, you can use other installed supported browsers as another option.

If the issue persists, I recommend contacting our support team. This way, they can take a closer look at your account and provide a resolution.
