Why do my Clappy value emojis show as codes?

In Clappy, the BuddiesHR kudos app for Slack, company value emojis show up as text when they were typed as Slack emoji codes, like this:

You probably entered a Slack emoji code like :clap: instead of a native emoji like 👏. Slack codes only turn into emojis in some places in Slack: Clappy's messages show values as code, and the web dashboard and emails don't know Slack codes at all.

To fix it, edit the value in the 💎 Company values section of the Settings tab, in the web dashboard, and replace the code with a native emoji. You can type it with your keyboard's emoji picker, or copy it from this emoji page. See company values.
