The Option key removes the layer in Photoshop 25

Hi!
The script:
1. I draw with a brush on a copy of the layer.
2. I press the "S" key for the Stamp.
3. Click Option key to select a sample.
4. If for some reason I don't right-click to select a sample, and press Option, then the current layer is deleted.
It's the same with the Healing brush.

If you don't use Stamp, etc. and just click Option key on the layer, then nothing happens to it.
