When a user creates a new Flow topic, we're currently putting two lines into all the logs -- one for creating the topic, and one for posting the first message.
This is an artifact from the days when users could create a topic without posting a first message. That has changed, and now it's just one action. The bug in watchlist + contributions that Helder reported is happening because the topic creation line isn't being suppressed.
The fix is: Suppress the redundant topic creation line -- the action of posting a new thread should be represented as a single action.
