Inventory Lab troubles. Anyone else having issues

Trying to start this whole new inventory lab and it's ridiculous. We are trying to send out a batch and it would not let us confirm the placement option we selected. It gave us 3 options and when we selected one option it took the carrier away (we wanted UPS).

We canceled all this and are trying again but want to know if anyone else is having trouble and how it got resolved. This is a headache and wish Amazon would have left things as they were!!!
