'when' statement skipping a condition in Kotlin for Android

I've been developing an app on android studio canary 5 using kotlin. I'm using a when statement to verify if a registration form is valid as so.

else if(registering) when {
        email.text == null -> email.error = "Enter Email!"
        !isValidEmail(email.text) -> email.error = "Invalid Email!"
        password.text == null -> password.error = "Enter Password!"
        password_conf.text == null -> password_conf.error = "Re-enter Password!"
        password_conf.text.toString() != password.text.toString() -> password_conf.error =
                "Re-enter Password!"
        password_conf.text.toString() != password.text.toString() -> password_conf.error = "Passwords Don't Match!"
        name.text == null -> name.error = "Enter Full Name!"
        branchSelected == "Branch" ->{
            val errorText = branch.selectedView as TextView
            errorText.error = ""
            errorText.setTextColor(Color.RED)
            errorText.text = getString(R.string.select_branch)
        }
        phone.text == null || !isValidPhone(phone.text) -> phone.error = "Enter Valid Phone Number!"
        !isValidReg(reg_number.text) -> reg_number.error = "Invalid Registration Number"
        roll_number.text != null && !isValidRoll(roll_number.text) -> roll_number.error = "Enter Valid roll number!"
        else -> {
            createAccount(email.text.toString(), password.text.toString())
            addDB()
        }
    }

The line password.text == null -> password.error = "Enter Password!" doesn't work for some reason.

I'm like 90% sure the line is correct since email.text == null -> email.error = "Enter Email!" works perfectly fine and android studio color codes the variables.

Can the error occur because android studio kotlin support is in beta or for some other reason?

Update: As JK Ly suggested, Here are the values of email and password:
