Sensor not getting all events from EventSource

[akunafin]

I've created a GitHub EventSource listening for release events. In GitHub, when I create a new release, I see it generates and sends 3 events at the same time:

• release.released
• release.created
• release.published

I see that all 3 events have been successfully delivered and in the EventSource logs I see "succeeded to publish an event" message for each of them. However, in the sensor logs I see only the first event, while other 2 events are missing. Also I see that trigger was executed only once.
Could you please help me understand what am I missing here and how to make all 3 events to trigger a task.
