FBX import into Mixamo is comically small

Hey All,

Pretty new and playing around with mixamo. Ive designed these characters that I'm try to animate but they are all getting uploaded so small that I cannot see them in the application. 

Is there something I can do to help the scaling? When I export it back out of Mixamo it looks fine. Ideally, I want to avoid scaling up the character prior to moving to Mixamo cause it gets a bit more complicated to downscale afterward.

Any suggestions would be helpful- thanks in advance!
