Old Custom Fields not shown or cannot be edited

Hi, we created Custom Fields such as “Salesman Name” in Invoice and we’ve been using it for quite some time. Now, we want to add new names under “Salesman” but we cannot find the old custom fields we were using anymore and can’t edit. Please advise.

Check under Settings>Obsolete Features>Classic custom fields. From there u can upgrade those custom fields to the new ones too.

Thanks. It’s working now! Appreciate it.
