cant control the duplicate objects using snap

I am trying to snap(cntrl+D) a simple gameobject while translate along one of the coordinate axis. The problem is I getting far many duplicate objects then I should get. I checked the snap settings to make sure values are set to one.

Thanks in advance

I’m getting the same thing. Not sure if you ever found a good solution, but for a current work around I’m using the “Ctrl/Cmd” + “D” to duplicate the selected object (overlayed on top of the original), then using “Ctrl/Cmd” while clicking and dragging the axis arrow to snap the duplicate in place. Holding “Ctrl/Cmd” + “D” is what causes the mass duplicates from what I’ve seen.

I hope that might be helpful.
