Hi
I had this exact issue when I was dealing with a 13inch MacBook Pro and is really easy of fix and doesn’t take that long!
What you have to do is open it up and go up to step 13 on the guide linked below! But instead of taking the screws out you loosen them and move your display into its place until you are happy with it:-)

If you need any help in the process just ask :-)
Hopefully this helps
Thanks:-)
