Why do some created form fields have more properties? Actions - Format - Validate - Calculate

I am new to Acrobat DC.

I have created a few forms.

On the first forms that I created, a text field for example, the tabs I listed above are NOT available in the text field properties, but in a form I just created today, they are. I am confused as to why there is a difference between the options on the two forms.

In both cases, I had a PDF file that I was using to make it into a form.

For example, in the first file, I have a phone number field, and there is no option to format it in the phone number format - like I can on the second form I created only has General - Appearance - Position - Options as tabs on the text field properties, and does not have the other options I listed in the question above.

Any help appreciated.

Thanks!
