keep ease settings when dragging keyframes

Hello everybody,

Dragging keyframes back or forth or copy pasting keyframes in the timeline changes the ease beziers.

For example:

“Left time ratio on 80” & “Right time ratio on 80” on frame 13
“Left time ratio on 0” & “Right time ratio on 0” on frame 21
… when dragging the first keyframe from frame 13 to 19 the values change to 45.71 & 320

I would like to know if I can change settings somewhere to keep the beziers from changing values.

Thank you.
