What it is showing in the screenshot (first one) is correct. It is showing how your profile looks like for others who are not following you or are not your friend on Facebook. It is not showing how it looks for those who are already following you. To see that, change the Public option with any of your friends' names.
Look at the Add Friend and Follow options. They are there, so it is showing anyone can send you a friend request or follow you.
For more clarity you can look into your profile from someone's profile who is already following you. You will see Like and Comment options will be there (if post is public).
So your settings are fine, just make sure when you are posting something you have set the audience as Public.
