Welcome to QuickBooks Community, @mikedrivertrucki.
The error may appear when there's an issue with the browser. This is the reason why you're unable to change your category when updating your transaction. The best thing that we can do is to perform some basic troubleshooting steps. This way, you can get back to your business.
First, use a private browser to access your account in QuickBooks. It is also known as InPrivate in Internet Explorer and Incognito mode in Google Chrome. This browser mode doesn't record the browsing activity on your local device. You can access this by pressing the following keys:
- Press Ctrl + Shift + N (Google Chrome).
- Ctrl + Shift + P (Firefox).
- Control + Option + P (Safari).
If you're able to alter your preferences, then let's clear the cache in your web browser or try using a different supported browser. It could be a temporary issue with QuickBooks and the current browser that you use.
Additionally, here an article that will help you in categorizing your transactions in QuickBooks: How to review downloaded bank and credit card transactions and put them in the correct accounts.
If there's anything else I can do for you, please let me know. I'll be around to help you. Have a beautiful day!
