Hello there, AlexisR. I'd be glad to help you with your concern.
To keep your purchase number sequence in order, we can use the actions I'll mention below to resolve this. This way, it can help us figure out what caused this issue.
- Logging in and out of your account.
- Turn off and on the PO custom transaction number.
Furthermore, if you've done the steps mentioned and the issue persists. I recommend using your incognito when working with your QuickBooks Online account. It can help your computer run optimally and regain some storage space to continue working seamlessly.
See these keyboard shortcuts to open a private window:

Also, you can try clearing your browser cache and use a supported browser so you can take advantage of QBO's full potential.
