Understanding Log Sources & Investigating with Splunk

Hello! Is there anyone who can help me with the Using Splunk Applications? I downloaded and configured Sysmon App for Splunk. But I couldn’t solve any of the questions. I am not sure if I did evrything right while configuring the App. Especially I am not sure with the macros issue. Neither Reports tab nor Network Activity gave me any result although everything seemed OK in the File Activity exercise. Could you please give me a hand? Thanks.
