MOVE TEXT TO THE CHAPTERS IN THE BINDER

Hi, under version 2.9 of scrivener the drag and drop for moving text does not seem to be working since it leaves behind the original selected text to be deleted. At the same time, I cannot move text directly to the text contained by folders/chapters in the binder. Both operations look to me as essential. Is there a way to do that?
Thank you.

Since this concerns the beta, it should be posted in the beta test forum, where it can be properly addressed: https://www.literatureandlatte.com/forum/viewforum.php?f=57.
