When I select several files in LR and Photo>Edit in…>Silver Efex Pro 2, Silver Efex opens on the first selected file; however, the other selected files are not available for editing there--i.e., there is no "next" button at the bottom. I have the latest LR and I reinstalled the Nik Collection, and selected the files in both Library and Develop modules. There is no other Silver Efex app on my Mac.
What am I missing? It used to work, and, now, for no apparent reason, no longer works that way.
