I am using it on an iPad.

Please tell me about the object tool.
For example, if there are layers with black and gray circles drawn on them, and the black circle layer is selected, when I touch the gray circle on the canvas with the object tool, the selection changes to the gray circle layer. Is this how the object tool is supposed to work?

If I draw a speech bubble on a tone using a tool, and try to adjust the speech bubble, if the tip of the pen touches the tone even a little, the selected layer changes from the speech bubble to the tone.
Anyway, the selection jumps to the layer depicted in the touched part, and if I move it without noticing, the drawing also shifts significantly accordingly, which is very annoying. I don't remember feeling this kind of annoyance before, so I thought that something had gone wrong with the object tool settings (?), but I also thought that it might have been this way from the beginning, so I asked the question.

Is the above behavior normal?
I would appreciate it if you could let me know. Thank you in advance.
