In the 1.11.2 version, I'm usually have a torch in my offhand, so a right-click places one. However, that conflicts with your tool placing option. The torch gets placed and then overwritten with whatever happens to be next to my tool. Very strange behavior.
Also, I guess it has something to do with this interaction, you can override blocks. So I right-clicked at the ceiling and the stone got replaced with a dirt block.
