[CS4 V4.12] Why wait for timeout when device finished job already

[Please move to correct category if this is the wrong one]

Chirpstack V4.12
Using integrated FUOTA service.
Setup a single device in the FUOTA deployment.

Jobs in the deployment always wait for timeout, even all (here 1 device) have already completed the job?

As shown in the logs, the device is marked as “completed” for each job after 1 minute, but the job still waits for 10 minutes timeout before it proceeds.
