Backend - auto filling fields on new subscription

Hi,

I'm using Membership pro on backend only cause subscription must be create or edited by administrators only (payment is offline).

When I create a new subscription, I see the registration form with all active fields.
The user profile fields are auto filled when I select a user. That's OK.

But dates and prices are not auto filled when I select a plan from the list.

Also, setup fee and payment fee are not hidden, but all my plans don't have fee and they have been setup like this (and payment plugin too).

Is it normal or there is a problem ?

I know, an administrator could let this fields empties, and the system will fill datas with the good values.
But that's not really ergonomic to use, and administrator thinking there's a problem could fill dates and prices with bad values instead.

Is it a way to improve this form ?

Thank for your answer.
