If you cannot find a form in the Add Form/Display Form list, then it is most likely that you may have the columns sorted incorrectly or by the wrong term. When viewing forms, across the top of the columns are four buttons.
One of these options will have either a gray arrow or a checkmark next to it, signifying that it is the current column being sorted right now. This also signifies which column you're searching through.
For example, if you have the Type column sorted and you're looking for Amendment, you likely won't find it. Now, if you have the Description column sorted, searching Amendment will result in finding the correct form.
