As anyone swapped an on/off Cartridge on a concealed shower and then when turning the knob full off it goes past the vertical position. On the picture the valve is off I.e no water coming out of the shower. But the top knob will move another 5-10 degrees to fully off/stop position. I can't take the knob off and re attach to get a better finishing point as it's kind is between two position. Hope that makes sense
