Timecard Creation using REST API

We are using the Time Card REST API (Timecard load), and I’ve noticed that regardless of the processMode value I pass, the time card is always created in the ENTERED status. I expected certain processMode values (like SUBMIT,SAVED) to create the time card in a different status, but it doesn’t seem to have any effect. The API completes successfully with no errors, but the time card still ends up in the Entered state.
