Topaz Studio 2 Unable to view file list

I’m on the latest version of Windows 10. Since loading the latest version of Studio 2
I am unable to view the file list after loading any number of images. There is no button showing at the bottom of the window to expand the file list, so can only edit one image at each session.
Are there any keyboard shortcuts to move to the next image or select all the images?
Thanks in advance
