Eyedroper Tool sees invisible things ( Corel Draw Graphics Suite 2025 )

I have a file with two layers. in the lower layer there is a red square and in the upper layer there is a blue square. But this layer is locked and not visible. If I now go over the red square with the eye-dropper tool, corel tells me that it is blue. The eyedropper tool does not consider the layer visibility correctly !!!
