Is LWF in Haryana paid for the month in which the employee left?

Is LWF in Haryana paid for the month in which the employee left? The system is not calculating LWF for the month the employee left the job. For example, if the employee did the job from 1st April 2021 to 15th June 2021, then the system is not calculating the contribution for the month of June of this particular employee.
Please suggest

was his salary for that month (paid for part of the month), less than the minimum PT slab?
If so, your software may be ignoring it for that purpose. Since you know it is wrong, just add it manually
