I uploaded another project to mine and when I went to time remapping the graph editor and it looked like this. The keyframes were eased, but it still looked this way.

it's normal, the dashed point mean that this part of time is set to the beginning or ending. so their are nothing to play is this time because you simply move the first and the last time remapping keyframe to the middle of your composition, the second dashed line i think it's the reference line or so.., you can click on (chose graph type and option) and remove the unwanted guid and line.
You are looking at a speed graph. Look at a value graph and you will see what you expect. Remember, that is 'time' that you are looking at, not speed. The speed graph is going to show you how fast time changes. Here's what it looks like with show reference graph and edit value graph selected. The clip speeds up, then freezes for a few frames, then continues and slows to a stop at the end.
I believe you also have shown all keyframes selected.
Maybe this will help:
You have Show Animated Properties selected so everything on the layer with keyframes is showing on the graph editor. The time remapping keyframes will not show bezier handles unless you select an individual keyframe or a line segment in the graph editor. If you turn off show all animated properties the graph should scale so you can see the slope of the time better. In your first screenshot, the time after the second visible keyframe seems to be almost a flat line. If it is a straight line then you have a freeze frame. I also see that at 15 seconds into the timeline you are five minutes and 34 seconds into the clip. Time remapping sets its first keyframe at the head of a clip. Because that keyframe is about five and a half minutes before the current time the scale is so compressed that it is almost impossible to see the difference in time values in your clip. A more efficient workflow would be to pre-compose the footage before you add any effects, then apply time remapping to the pre-comp. This would set the start value for the first keyframe at 0 and make it a lot easier to make adjustments.
You should spend a few minutes with the User Guide to get a better understanding of the graph editor. This also looks like an awfully long comp. I'm guessing that it is several minutes long. Unless you are using one shot that long without edits it would be a very good idea to trim the comp length to include only what will appear in the final edit. You're going to have endless preview and cache problems working in a comp that is that long. My average comp is under seven seconds. I may have hundreds of comps for a single film, but none of them include more than a shot or a short sequence.
I hope this helps. There is nothing wrong with your display that I can see. You are just not understanding what is displayed.
