Webform MySQL Views – display readable option instead of key

I’m using Webform MySQL Views to display webform submissions in a table, which is great.

However, when I add a webform field (where field type = select options), the result on the views table displays the safe_key (1, 2, 3, etc.) instead of the human readable option. How can I rewrite the results to display the readable value as opposed to the machine key?
