Problem with Merge: It only processes one file

Hello everyone!
I’m using N8N Cloud and I’m experiencing an issue with the Merge node. It’s only processing one file, and this is slowing down my workflow.

Goal of the workflow:
The flow collects data from multiple companies, filters and enriches only the necessary information, and then generates .xlsx files using the Convert to File node. At the beginning of the flow, OneDrive folders are also mapped so that each file is sent to the corresponding company folder. Merge receives .xlsx files and mapped folders from OneDrive.

Problem:
The flow sends six items to Convert to File, but as soon as the first file is generated, it goes to Merge and begins uploading to OneDrive. The remaining files end up stuck in Merge, without continuing the flow. Is there a way to configure Merge to wait for all files before continuing?

Thanks for your help!

hello @Eleva

Can you share the screenshot of the executed workflow? It’s quite hard to say what the issue might be.

But those three HTTP nodes in the beginning may mess up the merge inputs
