First things first, your flow is not importable. Please read How to share code or flow json and edit your first message (with a fresh export as the forum software messed it up in the current form).

If I can understand it well, you have 2 incoming nodes that you like to merge together. Have you looked at the join set to merge on topics and made sure that both incoming messages have a different topic?
