SuiteP Not obeying detailviewdefs.php - no filler cells

After switching to SuiteP, I can’t get an empty first column in Leads detailView page.
Whether using Studio OR manually editing ‘custom/modules/Leads/metedata/detailviewdefs.php’ thus:

    'panels' =>
    array (
      'LBL_CONTACT_INFORMATION' =>
      array (
        0 =>
        array (
          0 => '',
          1 =>
          array (
            'name' => 'assignment_status_c',
            'studio' => 'visible',
            'label' => 'LBL_ASSIGNMENT_STATUS',
          ),
        ),
        1 =>
        array (
          0 =>
          array (
            'name' => 'first_name',
            'comment' => 'First name of the contact',
            'label' => 'LBL_FIRST_NAME',
          ),
          1 =>
          array (
            'name' => 'lead_source',
            'studio' => 'visible',
            'label' => 'LBL_LEAD_SOURCE',
          ),
        ),
        2 =>
        array (
          0 =>
          array (
            'name' => 'last_name',
            'comment' => 'Last name of the contact',
            'label' => 'LBL_LAST_NAME',
          ),
          1 =>
          array (
            'name' => 'status',
            'studio' => 'visible',
            'label' => 'LBL_STATUS',
          ),
        ),

Anyone know what the problem is?

did you run a quick build & repair? do you have all your ownership and permissions right? does it work with other themes?

best regards

Yes, yes, and yes, Works properly when I switch to SuiteR (see attached screen capture)
