xml - Magento-Category Custom Layout Update - Correct .phtml file not showing on frontend -

i have created categories before , able have correct custom layout show on front end. when duplicating settings these categories correct layout not showing.

in custom layout update field:

<reference name="product_list">      <action method="settemplate">          <template>catalog/product/canada-grid.phtml</template>      </action> </reference> 

when re-index layout

<template>catalog/product/list.phtml</template> 

i have tried changing setting reason layout "list.phtml" , coming default folder , not current theme.

we have solved problem. custom layout update field needs uniform. if have multiple store views custom layout update xml code needs put on default store view store view want changes seen on.
