Trouble Joining Tracks

I am trying to create a map of my neighborhood trails. I have various tracks I have collected on the different trails. I've uploaded all of the tracks into a single track in BaseCamp. I would like to join some of the tracks together to form a single track. The help files say click on multiple tracks while holding down control and then using the join tracks under the edit menu. When I try clicking on multiple tracks while holding down control I cannot seem to select multiple tracks. What am I doing wrong? Thanks
