strange behavior in "Color Calibration"

Hello,

I have detected a strange behavior in one of the Ansel modules. Specifically in the "Color calibration" module.

I have observed the following:

1. I create a new instance of "Color calibration".
2. I duplicate this instance for the B&W preset.
3. I move the present over the "color balance RGB".
4. I activate the present for B&W and in the "History" it is duplicated. Now I have two "Color calibration" with the same numeral "1".

Now if I don't like the result and I want to undo what I have done, I go to "History" select the initial instance of "Color calibration" and....

The instance that I had duplicated is placed at the beginning of the module group "color".

If I compress the "History" to leave it as at the beginning, it is still at the beginning. If I activate it, this happens:

It cannot be moved (Ctrl+Shift) and I can only delete it. Or close Ansel and reopen it. Only then the duplicated instance disappears.

I have tried the same with "Exposure" and it doesn't behave like that.

My Ansel is an AppImage, specifically:

If I am doing something wrong, I would appreciate your corrections.

Note: I often duplicate this instance because I like B&W and this module is very versatile. The reason for placing it above the "RGB color balance" is so that it affects all the lower modules with respect to the modifications I have applied to them. It is the last module I use in the transformation to B&W.

Thanks for reading and trying
