find
$aValues = array_merge($aValues, $aDynamicGroups);
bellow add
array_unshift ($aValues, _t('_Please_Select_'));

find
return array(
            'type' => 'select',
            'name' => $sName,
            'caption' => (!empty($sTitle) ? $sTitle : _t(!empty($sCaption) ? $sCaption : '_' . $sName)),
            'value' => $sValue,
            'values' => $aValues,
            'checker' => array(
                'func' => 'avail',
                'error' => _t('_ps_ferr_incorrect_select')
            ),
            'db' => array(
                'pass' => 'Int'
            )
        );
    }
make changes
return array(
            'type' => 'select',
            'name' => $sName,
            'caption' => (!empty($sTitle) ? $sTitle : _t(!empty($sCaption) ? $sCaption : '_' . $sName)),
            /*'value' => $sValue,*/
            'values' => $aValues,
             'required' => true,
            'checker' => array(
                'func' => 'avail',
                'error' => _t('_ps_ferr_incorrect_select')
            ),
            'db' => array(
                'pass' => 'Int'
            )
        );
    }

So this works on the upload button (pseudo modal box) on photos and videos and such?

no clue, try it, if not add your other fix along with this one and it should.

thanks!
