I have next problem. I am trying to add section to the right to blue section but it’s displayed on the bottom of the screen

How I can make it correct?
<template>
<qp-fieldset id="fsColumnD-Request" view.bind="Document">
<field name="UsrPOCreated"></field>
<field name="UsrConcatReference"></field>
<field name="UsrMotivationReason"></field>
</qp-fieldset>
<field after="#fsColumnB-Request [name='Description']" name="UsrRejectReason"></field>
<field after="#grid-Details [name='InventoryID']" name="UsrWarehouse"></field>
<field after="#grid-Details [name='UsrWarehouse']" name="UsrTaxCategory"></field>
</template>
