I'm here to help you get everything back on track, @dhodgson. We'll work through some troubleshooting steps for your web browser to get everything running smoothly again.
I recommend refreshing the page initially. Afterward, under the For Review tab, filter by dates, transactions, or search by description to confirm whether those 42 entries are indeed missing.

If that doesn't resolve the issue, let's go through some troubleshooting steps for your web browser.
First, try accessing your company in an incognito window using the following keyboard shortcuts based on your browser type:
- Microsoft Edge: Ctrl + Shift + N
- Google Chrome: Ctrl + Shift + N
- Mozilla Firefox: Ctrl + Shift + P
- Safari: Command + Shift + N
If the transactions appear correctly in the incognito window, the issue might be related to your primary browser. Reopen your standard browser and clear its cache to remove any data that might be interfering with the platform's performance. Alternatively, you can switch to another supported browser.
Then you can go ahead and categorize them.
In addition to this, I recommend reconciling your accounts regularly to maintain financial accuracy. You can refer to the article Get bank statements directly from your bank when you reconcile in QuickBooks Online and follow Step 3 for guidance.
- Go to Bookkeeping and select Reconcile.
- Select History by account.
- Look for the statement.
- Select Attachments in the Statements column to open the statement.
I hope these steps help resolve your issue smoothly. If there's anything else you need assistance with, or if you encounter further issues with categorizing your transactions, please don't hesitate to reach out. I'm here to provide you with the support you need to keep everything running smoothly. Looking forward to hearing about your progress, and I'm just a message away if you need any more help!
