#8 Importing with multiple units doesn't render correctly

[akamua]

When importing a route, if more than a single unit is included, the scale table is incorrect.

To reproduce:
1) Create a route with more than one unit (i.e. Kilometes and Miles)
2) Export the route
3) Import the route

The scale table in the upper right hand corner is too small - looks like it is set up to handle a single unit.
