Thanks for posting an update here, @Skellytonne.

If you experience any unusual issues with your estimate templates, like styles not applying or missing fields, run some browser troubleshooting steps to fix it.

Unexpected issues in QuickBooks are sometimes affected by the amount of data stored in the cache. This is because a regular browser will constantly overwrite the data and will not remove history unless done manually.

Private browsing will not save any history, so it's a great place to identify issues in the browser. Use these keyboard shortcuts to launch a new private window:

• Google Chrome: press Ctrl + Shift + N  
• Mozilla Firefox: press Ctrl + Shift + P
• Safari: press Command + Shift + N

Once done, check if the custom field appears this time. If it works fine, clear the cache to resolve browser issues in QBO. Using a different browser can also help.

However, if the same issue persists, I recommend getting in touch with our Support Team. They can help report this to our engineers who can help with program bugs and other technical concerns.
