I think that's expected.

The vrr_enabled property is a default one in the kernel for 5.0+ but 
doesn't exist before that. Since it's default and could affect other 
test results if left enabled from another test I chose to add it to the 
list of default properties being reset. So it was probably missing the 
property in those tests and failing.

I don't know which version of the kernel was running the test but I 
don't think it was 5.0 at least (considering the date it ran).
