Hi Silivio,
This is general behavior of Transport Management, not having any relation with Change Request Management.
Lets take example, if any TR is imported in from Dev to QAS than by default it will be available in Production import buffer. So similar to your case if TR is imported in Dev system than it will be available in QAS import buffer and ChaRM consider those type of TR as ready for import.
From ChaRM side, it will be imported once you execute "Pass Change to Test".
Please let me know if it is clear to you.
Regards,
