Thanks for joining this conversation, @Nolstev.

Just to confirm, are you also trying to change detail type of a parent account? If so, you should be able to do it after clearing the sub-accounts.

As an initial troubleshooting step, try to use a different or a private browser. There are times that the browser is full of frequently accessed page resources, thus causing some unusual responses. To use a private browser, here's how:

• Press Ctrl + Shift + N (Google Chrome).
• Ctrl + Shift + P (Firefox or Internet Explorer).
• Control + Option + P (Safari).

Once logged in, change the account detail type again. Here's how:

1. Go back to the Chart of Accounts and locate the sub-account to change.
2. Click Edit under Action column drop-down menu.

3. Change the Detail Type.
4. Hit Save and close, then Yes.

If it works, return to your default browser and perform clear cache. Clearing it will refresh the system, and you'll be able to work with a clean slate.

I'm also adding these articles for additional resources:

• How to view or change account detail types.
• How to change the type of an existing parent account or sub-account.

That should get you fixed right up. Keep me posted on how everything goes in the comment. I'll be happy to answer if you have any follow-up questions. Have a good one.
