Thanks for the details you've shared, @Mark381.

I've checked the QuickBooks Online US version settings and saw that this is available. I'd suggest performing browser troubleshooting steps. The accumulated data in your browser will become obsolete over time and may cause odd behavior to the program. In this method, you'll be able to verify if the outdated data caused the issue.

You can use an incognito browser to start the verification. If you can see the Late fees option, you can go back to the regular browser and clear the cache. This is done so that the data will be refreshed and replace by the updated ones. If it's still the same, you can use another supported browser as an alternative.

You can refer to this shortcuts keys to open a private browser:

• Google Chrome: Ctrl + Shift + N
• Mozilla Firefox & Microsoft Edge: Ctrl + Shift + P
• Safari: Hold down ⌘ + Option + P
