In previous Stat versions when creating new CSR the User id field would be blank and user needed to mouse click on user id drop down and select a user.
In 5.8 when creating new CSR the user id field will default to queue owner but user can still mouse click on user id drop down and select another user id before saving a CSR. So the functionality is still the same. This is how it works in 5.8.
You could submit an enhancement request to revert back previous functionality explaining your needs to have the functionality like it worked before.
