Typing in Enter key when searching in Form fields is creating a Document Template

1) Create a new Document template

2) Upload a PDF form

3) Go to the "System Fields" and type "Postal" to filter the list and at this time if you hit the "Enter" key - the page/form is submitted and the template is created.

The User hit Enter to finish their Search and didn't mean to submit the form. Can we disable the Document Template form Submit when they hit the Enter key
