Opening the conf menu with the button in the wand menu seems to increase the dropper/dispenser click sound effect that plays when any buttons in the wand menu are pressed. Exiting the conf menu and pressing the button again further increases the volume of the button sounds.

I've boxed the button I'm referring to in red in the attached image.

Closing the wand menu resets the volume back to its original setting.

Also, I can't figure out which volume setting will change that sound's volume, only the master volume seems to change it.

I'm getting the same issue in 1.19,2

A similar volume issue occurs when using grid mode, incrementing the width is normal volume while incrementing the height is very loud
