mad_libs Correct but not displaying Correctly

[alieana008]

I've completed the mad_libs function in Lesson 9 and when compared with the correct answer (mad_libs-correct.R) it is identical. However, when you run it, it says it is correct but it doesn't actually display the provided arguments within the printed text. See below:

Since it says this is correct, I'm not stuck or anything, but I am intrigued as to WHY it isn't actually displaying the text. With only a few lessons under my belt, I don't understand R well enough to know why this is happening or how to fix it, or similar issues I may come across, in the future. I'd appreciate any responses if someone has an answer, and it would be nice if the lesson were fixed to ensure no one else encounters this issue in the future.
