AzureDevops pipeline - Test result trend does not match test reult

I have a scheduler job in azure devops that runs nightly and the test result report is almost like this for each day. Some passed som failed etc. 

but when I  check the trend link, it is like this 

What I do not understand here is, why the trend only shows the failed and not the passed tests. Is there any thing in config anywhere I can change to fix this?
