Error in process template with <configuration id="ti

Hi team,

I have a problem in my process template in RTC 3.0.1:

<configuration>
<timeTrackingSpecification>
<configuration>
<timecodes>
</configuration>

</configuration>In the bold line " <timecodes>", show the next error:

cvc-complex-type.2.4.b: el contenido del elemento 'timecodes' no est completo. Se esperaba uno de '{"http://com.ibm.team.tpt/timetracking":timecode}'.

I have searched in several pages but I have found nothing.
I don't understand this error. Could you help me??
How it works exactly??

Is it something about the planing section?
