Gismo - Topography curves not working

Hi!

I need to read the topography curves from a terrain in these coordinates: -12.5034,-37.9672

Actually, this is a terrain in a middle of nothing. 

When I put it to location and then in Terrain Generator,  everything seems to be working fine, but the curves I get are not the same curves that I should get. When I search at opentopography, I saw that there is many other curves that are not represented in my rhino view. Do someone know how to solve these problem?
