Objects not getting released from Transport after moving to Production

Hi,

I have moved few transports from Development system (DEV) to Production system(PROD).

But as per the process, once the transport gets imported to PROD, the object(OBJ) that are present in the transport should get unlocked automatically.

Now the problem is, The Objects that are present in the transport are not getting unlocked in DEV even after the transport is imported to PROD.

While the developer is trying to use the Object OBJ in DEV, it is showing a message that the OBJ is locked under some transport.

We can release the locks manually, but earlier this happened automatically.

Please suggest what might be the issue.

Thanks & Regards,

Bharath.
