Convert track to stereo [SOLVED]

[IndieDev]

Hi, I have created a track with a VST instrument but for some reason the track was created in mono, that is, it is only heard on the left channel and I cannot pan it to the center.
Why did this happen?
How can I convert the track to stereo?

You don’t say or show what the instrument is. Can’t see the dialogue boxes in your screen shot. 
The setting you want might be in the VST itself.

If it is really a mono plug-in change the track interleave to mono.

 

The interleave button is at the bottom left of the track header and the left most button on the first row of buttons above the pan knob in the track inspector and console view strips.

Thanks guys, that little button was the solution.
