Transport requests duplicated

Hi experts.

I have a problem with the transport system. I have a development and production system. Last week, I did a system copy from pro to dev system. Then, I reconfigured the transport system, I did a test and the configuration was transported without any errors.

The problem is that all tasks of the request also are inserted in the queue of the production system. For example:

Request: DEVK900334 Test

Task: DEVK900335 Repair

Task: DEVK900336 Develpment/Correction

Import queue:

DEVK900335

DEVK900336

DEVK900334

The tasks are visualized with return code 0, while the request has a status "No imported yet".

If you have any idea, please answer me.

Thanks in advance
