Quickbook unable capture the reference number I type. For example, I type 'PV 2307-010' but it auto capture it as 'PV 2312-023'. Why?

Let's work together to determine why the reference number you input changes to a different value, long.

We can perform basic troubleshooting steps to know if you're experiencing a browser-related issue. First, open your QuickBooks Online (QBO) account in a private browser or an incognito window. Depending on the type of browser you are using, please refer to the keyboard shortcuts provided below:

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Microsoft Edge: Ctrl + Shift + P
• Safari: Command + Shift + N

If there's no issue using a private browser, go back to your regular browser and clear its cache. Clearing the cache will reboot the system, allowing you to work with a clean slate. You can also use other supported browsers.
