Do single hung windows use two tension coils?

I am replaced the broken parts on a single hung window. I used parts I recently purchased that you suggested would work. My problem is when I open the window the sash clip drags on the coil guard and the clip either breaks or the plastic guard is chipped. What am i doing wrong? The window takes the 3/8 boot. It had two coils on each side. Help.

The window opens and closes with out damage but only when I use the sash clips to open the window and close the window when the clip is near the coil.
