Thank you for bringing this to my attention. Let me help provide you with steps to resolve this error in loading transactions.
If this issue occurs with all your customers, I'd recommend checking if this is a browser issue. You'll have to log in using a private browser first to determine if this is the case.

If you're able to create the invoice using the private browser, you'll have to delete or disable cache to resolve the issue on your regular browser.
However, if this issue only occurs with certain customers, you'll need to contact our Online Support Team so they can check this further.
Please don't hesitate to reach out again if you have other questions about your transactions. I'm here to help.
