Cue points and energy points

Please, why do I find that some tracks have cue points and other energy points, or both? as it appears in the image, and this is how it appears on my Denon device. That is, with the name that appear in LXC they are displayed in my SC5000M.

How can you change the name of those memorization points?

These cues are probably from Mixed in Key?
