The PS mobile tool dragged the whole group. What happened?

Just change the default value of "Group" to "Layer" on the right side of the property bar of the selection tool. ? I'll send a picture later. When you don't create a layer group, the default is "group", and the selection of a single layer will also be automatically selected. If you create a layer group and select any layer in the group, your problem will appear. So if you set the positioning attribute as "layer", you will block the layer group and only identify the layers.
