Zoho Project does not capture the correct billing status ("Billable" vs "Non-Billable") from Zoho People. 

This bug happens when:

 1- In Zoho People, a Time Sheet is deleted

 2 - A new time sheet for the same parameters (date, client, etc.) that was found in the timesheet above is created

 3 - A time entry is changed from "Non-Billable" to "Billable" or vs versa 

 4 - The Time Sheet is sent for approval and approved

 5 - The time remains "Non-Billable" in Zoho Projects even though it was changed

This was posted in both Zoho People and Zoho Project forums as I am not sure if it is a Project or People bug.
