Can't change symmetry to 4x...

[iceicespace]

I'm in the 3rd tutorial. Brick wall. 

I'm supposed to put 4 fins on by toggling symmetry to 4x. When i click the symmetry button, or x, i get the options of single, or double. What could i possibly be doing wrong...

You are in mirror mode. Press R to go back to Symmetry mode
