In your case:
Mono tracks should usually have one pan slider
Stereo tracks two
If a mono track has 2 pan sliders, there are various explanations:
	-you put a ladspa plugin (like a stereo panner) with stereo out
	-you put a send route with 2 outs 
	-you have mono plugins wich are doubled for no real reason.

Unfortunatly i had the last problem a lot, during my migrations. It seems that 
ardour doesn't check well when plugin should be doubled or not. 
If this happen you can check, in the xml file, the ladspa section for your 
route. Look if you see a mono plugin with count="2" . If it is a mono track 
it should be count="1" (please backup first changing anything)

Probably a mismatch of number of in/out with you plugin and the nature of the 
track (mono/stereo). I had, a few times, some similar problems. A mono plugin 
was not doubled on a stereo track when it should. You can check as well the 
xml song for inconsitancies with the "count" parameter.
