TV naming questions

I am very new to Plex and making my first attempt with TV shows. I have a show named Dick Francis Mysteries with one season and three episodes within that season. My folder structure is:

Dick Francis Mysteries
Season 01
Dick Francis Mysteries - s01e01 - Twice Shy
Dick Francis Mysteries - s01e02 - Blood Sport
Dick Francis Mysteries - s01e03 - In the Frame

When I look at the TV Shows library I see an icon for Dick Francis Mysteries Season 1 and the icon has the number 3 in the upper right corner to indicate the number of episodes. The icon has a play button in the center but I cannot find a way to see a list of the episodes and choose the one I want to watch. What am I doing wrong? Thanks.

click on any part of it except the play button in the center

Perfect. Thanks.
