Soloing Either Channel Always Plays Back On The Right?

To solo 1 channel of a 2 channel, stereo file, I press the “Alt” key and left click either on the left, or right channel. This plays back the individual selected channel as expected. However, either of the 2 channels plays back on the right side; The right plays back on the right and the left plays back on the right, too. Is there a way to solo the left channel and hear it on the left side? This is in Wavelab Elements 10.
