The For Each Email sequence is not working as per design

Hi there,
I’m learning for the certification and was following the Associate learning path. In the course Build Your First process with Studio (UiPath Academy) when I was running the automation as per the Part two of the video, my For Each loop is not working as per the design of the process.
It opens the first of the Excel files, uses its client code, and updates all the invoices (Excel files) with its discount values only.
Your help and guidance is highly appreciated.
