I don't know what labels it is referring to but it isn't the road names because I already tried it.

There isn't an option "Never English when you are in a Spanish speaking country"

EDIT: Just thought to close the app and relaunch it. Now I have Spanglish

Calle 52, Calle 52A and then Street 53

Avenue 13 but Carrera 15

Avenue Cir Cunvalar which should be Avenida Circunvalar

Avenue Alberto LLeras Camargo, and Road 7, both of which should be Avenida Séptima.

Avenue Nos which should be Avenida NQS or Avenida Norte Quito Sur

Av Street 72 which should be Avenida Calle 72 or Avenida Chile

Autopista El Dorado which should be Avenida El Dorado

Av Street 24 which should be Avenida La Esperanza

They really made a multilingual botch of it
