Issue with perspective login

Hello,
I have a project with foru users and assigned with two roles for the respective users (Operator, Administrator). I am able to login using all the four user credentials when launched with vision.

There is a problem when launching perspective as I am able to login using only two users credentials and one fall under Operator role and the other under Administrator role.
I am not able to login using all the four user credentials
Can you please help me out with this issue

Thanks in advance!
