The application profile name is case-sensitive.

$ sudo ufw app info OpenSSH
Profile: OpenSSH
Title: Secure shell server, an rshd replacement
Description: OpenSSH is a free implementation of the Secure Shell protocol.

Port:
  22/tcp

If you take a look at the definition file, it is very simple.

$ more /etc/ufw/application.d/openssh-server 
[OpenSSH]
title=Secure shell server, an rshd replacement
description=OpenSSH is a free implementation of the Secure Shell protocol.
ports=22/tcp

Custom files may have multiple ports and ufw app interface make it is easier to manage.
