Cannot deselect or remove keyframes

Hello, I’m having difficulty removing these keyframes.
You know that sometimes there are three layers of keyframes right?
So I selected a part of the animation and erased “all layers” but one layer stayed.
Now I cannot erase it or deselect it. also if i click on a keyframe it does not
get selected unless I use the circular selection tool or box select.
Verry annoying.
