The error message "Undefined Column" in the timesheets view suggests that there may be a problem with the configuration of the timesheet view in Odoo. The specific error message "V13" may refer to a specific version of the timesheet view.

Here are a few things you can check to troubleshoot the issue:

1. Verify that the timesheet view is correctly defined and linked to the correct model. You can check the XML file for the view to see if the columns referenced in the view exist in the model and that they are correctly defined.

2. Check that you have correctly installed the module which contains the timesheet view.

3. Confirm that the module that contains the timesheet view is correctly configured and activated.

4. Make sure that your Odoo version is compatible with the module version

5. Check that the fields that you expect to see in the view are present on the model and that the fields are spelled correctly.

6. Check that the data on the model is correct and that the fields are populated with values.

7. check if the fields that you expect to see are present in the view, if not check for the inherited view for the timesheet view
