Hi @darko ,
Thank you for suggesting the possible cause of the issue. However, I am running into a different issue now which is, that I am trying to check both systems by deleting a test lead from Marketo only. Before deleting, I am making sure the custom field "Sync to Marketo" becomes false. Post that, I waited for half an hour to make sure the sync happens between the two system.
