It looks like the custom output is working differently for drop-down choices.

Here is an example:

Question: What is your favorite color? (single-selection drop-down)

When not using a custom output format, it displays fine, like this:

What is your favorite color?
Blue

Using a custom output it looks to display the number of the choice, rather than the choice itself, like this:

This is the custom output:
{username} tells us that their favorite color is $q[30].

(username) tells us that their favorite color is 2.

It seems to work well for the normal text fields.
