Transferring Routes from Basecamp to 3450LM

So I'm having one of those frustrating times you come across with IT goodies and I need some help/advice.

Now as a bit of background I was using Basecamp to plan some upcoming travel in Africa and had planned to move them to my 2360 which I soon found did not accept transferring route/trips.
So I did a bit of research and picked up a 3450.

Now I have transferred, using Basecamp, the various waypoints and routes I had planned and strangely only 2 of the 5 show in the Trip Planner. They all show in Basecamp after plugging the device back in and checking the internal storage

There is no real difference as to how the routes were created.
One of the routes that successfully transferred has more via points than the others. I can't for the life of me figure this out or find any information online.

I do see on the latest Basecamp that it has a Trip Planner feature but I don't really want to have to create the routes again and can't seem to find how to convert them.

Thanks in advance
