If you select some profiles to be installed when creating new container, they are displayed at the left side of the page. It is possible to remove them from the selection by a red cross on each profile's line. But this removal doesn't update the selection of the profiles at the right side of the page.

If you click "Create and start container" then, new container is created with profiles displayed at the left side of the page.

All procedure can be seen in the attached video.
