Scheduled Job running twice

NB version- 7.5.0.4

Master Server- Win08

Client - Linux

I have calender schedule for a client to ran at 11:40:00 PM 

Schedule detail for full backup-

Start Day- Fri - 11:40 PM

End Day Sat- 01:40 AM

So backup starting at 11:40 Pm and completeding at 11:41:30 PM, i see again job is auto starting at 12:00:00 AM just after 20 min.

Retries after run day is not enabled.

I see this for all client under this policy.

Can you corrent where i am wrong, why this job running twice?

I see there is bug in 7.5.03 but this is resolved in 7.5.04.
