Describe the problem/error/question

Hi all, I’m having some trouble whith some workflows, I have two workflows, the only diff is a noop node, but they get wrong outputs, both of them.

wf1 wo/noop:
Should output 1 item, but outputs 0
wf2 w/noop
Should output 1 item, but outputs 2

What is the error message (if any)?

Output:

Please share your workflow

Hey @ricardo_ned, perhaps you want to head to your n8n cloud dashboard and update to n8n version 1?

This version will introduce a new execution order which will affect nodes with multiple inputs (like the Merge node):

Once you have updated to v1, your example workflows will return the single item you expect.
