Switch and merge node

I know that the merge node needs to receive data on the 2 inputs, and when it doesn’t have it, it requests data from the previous node.

But I’m having a problem, even one of the previous node having data it requests another node which returns 2 items.

did I make a mistake in the way I set up the flow?

Can you please share screenshot including the trigger node. Thanks!

yes i can, no problem
