as you have only showed parts of the snip, i would say try and replace the part you showed with this
<container>
<attachment_group class="horizontal_arrange" horizontal_alignment="left,extend" horizontal_gap="0"/>
<container class="main_box" width="90">
<layout class="stick_to_sides_attachment" apply_to_children="true"/>
<container id="PerP" class="client_object_viewer_xml_panel">
<layout class="stick_to_sides_attachment" apply_to_children="true"/>
<widget class="object_portrait_picture" image_alignment="centre_x,bottom" scale_picture="true" keep_aspect_ratio="true" clickable="false">
<record id="object_property" get_property="objt" set_property="objt"/>
</widget>
</container>
