I have troubleshooting recommendations, @awesumjobs.
You can sign out and sign in back to your account. It will help refresh coding data such as font color and font style.
If the issue persists, I suggest using a private browser. Private browser mode prevents cookies from making QuickBooks store unnecessary text files.
Open a supported browser and here's the hotkey:
Safari: Press Command + Shift + N
Firefox: Press Ctrl + Shift + P
Microsoft Edge: Press Ctrl + Shift + P
Chrome: Ctrl + Shift + N
If this fixes anything, clear your browser's cache. It helps rebuild the cache that can help download fresh copies of data. It even boosts the browser's performance.
Otherwise, use another supported browser.
Before I carry on, may I know what browser you are currently using? It helps me find fast fixes in the future.
You can also check this article about using an estimate and split it into as many invoices as you need: Set up and send progress invoices in QuickBooks Online.
