Several issues with the "Select Approvers" Field

Several issues with the "Select Approvers" Field

(Post relevant to ServiceDesk Plus build 9117)

Hello

I created a service request template with the field "Select Approvers", so the requester can choose the approver himself.
I marked this field as mandatory, but this doesn't work. It's possible to save the request without choosing an approver.
When I want to edit this request, the field isn't there anymore.
In the Field & Form Rules it's not possible to choose this field either.

I made some screenshots. See my attached document.

Regards, Markus
