Bug in the API?

Is there a bug in the search part of the API? I’m developing a companion app that listens for the mood playing by performing a search (/search/?playing=Playing%20Now&format=json). Works a treat on what I thought was all moods. But in testing the Sticky Situation oneshot I noticed my app wasn’t showing the playing mood. The API search call also show no playing sounds at all, which isn’t true because I can hear them.

In the screenshots I have the Goblin Arrows Aftermath mood playing and I get an expected result in the API. If I then switch to the Sticky Situation Ailwen Manor mood, the API search returns 0 for what’s playing. I’ve checked direct on https://syrinscape.com/search/?playing=Playing%20Now&format=json and I get the same 0 playing result.

A bug? Could you guys take a look please?
