The use case you are trying to achieve is very sensitive to the Counter step — even minor changes can disrupt it. When we click on 'Save & Send Test Request', the Final Value changes, and during automation, it starts updating from that row. For example, if it shows as 4 in the workflow setup, the first row that will be updated during automation will be 5, then 6, and so on. So, you need to make sure that the Final Value is set to 1, so it starts updating from row 2 during automation. We just made that minor change, and it worked.
