Graph ? totals

I was looking through my graphs, "total distance".  As it turned out i did two workouts today bike and swim, however in the graph its puts both of these workouts in the same column.  SO i did 22 miles bike and 12.5 ( x 100 yds).  The graph added these numbers and put the total on top of the column.  It looks like i did 3500 yds swimming.  

 Is there anyway to split this up or have the graph not add the 2 totals together.
