I think the Snap module on my CB is somewhat broken. With Smart Grid disabled, I switch the module size from Large to Medium and select "1/16" etc. and then switch it back to Large and the snap resolution on the button automatically changes to "1/4" (but it still snaps to 1/16). The issue I mentioned above must be something to do this.

Another dumb 'smart' feature. Sheesh
For this reason I always use my custom project template, in which Smart Grid is disabled.
