Here is what I am doing: with my Android phone as a control point I select the album and hit “Play” to play immediately. When the album playing is done, roon continues to other “related” albums (same genre, same performers) from my library. I could not see how it can be disabled.
It seems that you have the Radio Feature enabled. I believe that this is a default setting that can be turned off.

Thank you, Mike. Will try it later at home.
