I wasn't able to replicate this problem in our test OJS installation. When an article has been assigned to a section editor, gone through review, and then sent to editing, the article moves from the Review Queue to the Editing Queue. When logging into my User Home as a Section Editor, if I click on my role as a Section Editor, I do see that I have no submissions. However, that is because it takes me to the Review Queue by default. When I click on my Editing queue, I still have access to the submissions to which I was assigned. If you are not experiencing the same thing, can you please provide more information, such as the version you are running?
