Windows Vista Double folders showing up - whatzzup with that?

I did a search for "double+folders" and did not find anything. Here is my dilemma.

When I go Start/Documents the Documents folder opens and I see all my sub-folders. No problem there.

But, in the tree to the left I see two (2) folders named Documents. The top one in the hierarchy has the sub-folders in it, and the bottom on is empty.

However, if I right click and delete the second folder, it sends all of my documents to the Recycle bin!

This started showing up earlier in the week after I installed a suite of Garmin software and the drivers to manage a GPS. I need my mapping and device software so if it comes down to it I guess I can adjust and live with it, but there has to be a fix.

How can I get rid of that second folder in the view?

Thanks in advance,
Rick
