i have used transform in lightroom and have edges that are blank. When I open this photo in photoshop the edges are are auto filled. i do not want this to happen. I have tried everything I know to prevent this. only happened after update to 27.11.1

In lightroom I use transform to correct perspective on raw file. I usually use guided. I then open in photoshop via  the edit in command. The blank edges are now automatically filled (and very poorly). There is only one layer and no clear way to stop this happening. I really do not want this to happen.
