Publish Service in Lightroom Classic

I opened a few galleries in TTG Publisher and the interface no longer looks like it did the last time I used it. There are no longer the options to update or delete images. The only option is to pubIish.I have Backlight 5. What am I missing?

Is it necessary to upgrade to Backlight 6 for TTG publisher to function with latest version of Lightroom Classic?

Thanks, Paul

To update, right-click on image and choose “set to republish” or words to that effect.
to delete, highlight image and hit the delete key.
After doing either of these, click on the Publish button.

As far as I can remember, it’s always been this way.

And usually, if you make a change to an image in an album, it will show in a “To be republished” (or words to that effect) section of the album.
