Thanks for coming back, @sarah175.

Changing your account preferences or unchecking the option to mark all expenses as billable won't affect or change the previous items or transactions created. The changes only affect the transaction created after unchecking the Make expenses and items billable box. If you created a new one, we can perform some basic troubleshooting steps to isolate the issue.

At times, the accumulated cache in your browser causes odd behavior when creating transactions. Start by accessing your account in a private or incognito window. You can refer to the shortcut keys I've listed below:

• Ctrl + Shift + N for Google Chrome
• Ctrl + Shift + P for Firefox & Microsoft Edge
• Command + Shift + N for Safari

If it works, go back to your regular browser and then clear its cache and cookies to start over fresh. Alternatively, you can switch to other supported browsers.

Feel free to visit our Expenses and vendors page for more insights about managing your vendor transactions. 

 You can always leave a comment below after performing the recommended solutions as I'd like to ensure this is resolved for you. Have a great day ahead.
