The number of likertSteps is between [2, 9], not just 2 or 5. 

For now, please fix this temporarily by change line 490 to the following:
else if (self.question.likertSteps  > 2){

This is not the final solution, since ideally we want the left and right labels to be on the same line as buttons when the number of likertSteps is [2, 4]. However, the block of "if (self.question.likertSteps == 2) " is hardcoded right now.

We will need to create a separate issue ticket later.
