Thank you for those informative screenshots.
I assume it didn't create a new element but moved the element "tecnica" with id=20 from trash back to view.
Is this possible? What are the groups in your elements listing (they are just cut off).
"tecnica" (id=10) is moved as expected, tecnica (id=20) is a linked (=child) element which is modified automatically if it's parent (tecnica id10) is modified and so changing it's status from trashed to the parent's status "published".
I can replicate this behaviour.
For changing the element order you don't need to edit the element. A click on the ^v column (beside the id column) will enable the drag/drop option: you can drag/drop the element to it's position.
