Timeliner task starting date issue?

[li71we]

I am using timeliner to create a amination.  Howerver ,  I foung if I change a task default starting date from N/A to a specified date , I can't change it back to N/A. 

Does anyone know how to set the task starting date or end date back to N/A for Timeliner?

Thanks

This should be accomplished by editing the date and pressing the Del key.

Hope that helps,
