Customizing the Opportunity ListColumns in other modules

[Svemar]

I have changed map to include created time instead of modified NAD removed the lable:
<map>

<originmodule>
  <originname>Potentials</originname>
</originmodule>
<relatedlists>
 <relatedlist>
   <module>Accounts</module>
   <linkfield></linkfield>
   <columns>
     <field>
       <label>Opportunity Name</label>
       <name>potentialname</name>
     </field>
     <field>
       <label>Related To</label>
       <name>related_to</name>
     </field>
     <field>
       <label>Contract</label>
       <name>cf_630</name>
     </field>
     <field>
       <label></label>
       <name>createdtime</name>
     </field>
     <field>
       <label>Amount</label>
       <name>amount</name>
     </field>
     <field>
       <label>Closing Date</label>
       <name>closingdate</name>
     </field>
     <field>
       <label>Assigned To</label>
       <name>assigned_user_id</name>
     </field>
   </columns>
 </relatedlist>
</relatedlists>
</map>

Results are the same -> no values from NON Potentials table:

Maybe the problem is related to naming. At database it is Potentilas, but on other areas it is Opportunities
