Webaudits report gives different results as compared to actual google lighthouse from Chrome browser

Hello team,

I am working with TestComplete Webaudits. In that, I have a simple test where the user navigates to login and then performs the web audits.
I am getting a different result when I manually check the web page performance in google chrome light house. 
For example, below is the result from google chrome lighthouse without TestComplete

and here is the result from TestComplete 

Does anyone know why I am getting this difference? 
Thank you in advance!
