Impossible to move indicator to last frame

The CTI (Current Time Indicator) in After Effects is always at the start of the current frame. In your screenshot, the comp is only 6 frames long. That means that the last frame starts at 5 frames so that is where the CTI stops when you move to the end of the composition. Frame 5 has not played yet, when it does, the comp will end at 6 frames. If you set the out point of a layer (Alt/Option + ]) you will always see the last frame because it has not played yet. 

After Effects has always worked this way. You can move the CTI to the end of the last frame by pressing Ctrl/Cmnd + right arrow if you want, but the comp panel will then be empty because the video is over. 

This is different than an NLE like Premiere Pro. When you cut a layer, the cut is made at the end of the frame. After Effects is not a video editing app and it makes more sense to see the start of the frame you are on when doing animation so you can accurately set things up. All animation and compositing apps work like this. On the other hand, when you are editing a video, the standard practice is to go to the spot where you want the next cut to start. That's the way cutting a movie has always worked, you cut the film, the tape, or the digital movie where you want the next cut to start. That is why the behavior of the CTI is different in an animation and/or compositing app than it is in an NLE.
