I'm fairly new to routing so I’m just sure I missed something basic here but,
When I try to insert a new route into a model with previous routes I can only chooses the tube OD from the previous route sizes. As in the picture its only letting me choose .625 OD options in the drop down menu but the new hose is 1.375 OD.
The hose I use has a table that includes the 1.375 OD options (it’s the basic routing hose Solidworks provides for tube routing I've attached it to the post) but I can’t select anything but .625 in the drop down menu.
What am I missing here?
At first glance their doesn't seem to be anything amiss with you tube part or design table.
So most likely you're doing something wrong while trying to create a new route.
Try this :
Now all this may be kicking in open doors to you but without more information from what steps you actually take it's not easy to see where something goes wrong. If the above therefor doesn't help then please provide additional information of what you experience and what steps you took that led you to that experience.
Have a nice one

ps: I attached an ASM that shows using 2 different tubes (using your tube-part)
