It seems like in 2.10 they reworked the selection tool in GIMP 2.10. I used to be able to use the rectangle selection tool, drag over an area and use the move tool to move that selection. When I try to do this in 2.10 however, I end up moving the whole image.
Upon searching it up, I only found 1 forum thread talking about how you need to 'commit' the selection by pressing Enter. When I do this it focuses on the selection and blacks out everything, shown in the link below. How do I get out of this odd mode and how do I use the selection tool to copy or move a selection in GIMP 2.10?
After I use rectangle select tool to select a part of the image and then press Enter to confirm my selection, I get this:

The image shows yellow dotted line around the whole image and the selection is shown but nothing else is.
