Good day, all!

I looked through the discussions, yet cannot find the answer. I have a paper and in it has these keywords: Reentry, Incarceration, Recidivism, Development, Theory of Verbal Behavior, Social Disorganization. I copy this to tags, and it adds it as one line, what am I doing wrong so they are added as individual tags (and I am not looking to copy and paste, delete, then go to next line. Is there a way?

Thank you!
