Shift+Click doesn’t work

I have Shift+Click set up. However, it outputs the same as CMD + SHIFT + Click, not Shift + Click as I set it up.
Does anyone have this problem or can help me?
Thanks

Device information:

  • Type of Mac: Macbook Air M2
  • macOS version: Ventura 13.3.1
  • BetterTouchTool version: 4.516

How did you check it is outputting cmd+shift+click ? I don't think that is possible.
Here is a simple mouse event viewer that let's you verify: Mouse Event Viewer

Thank you for responding.
I tried the installation operation on BTT and the manual operation CMD + Shift + Click and found the same results.
However, maybe I made some mistake, I will check again and try with mouse event viewer.

I tried checking again.
The above error occurs when I use Arc Browser.
Thank you for your support.
