Looking at Unamuno's Abel Sanchez..

'hermanos' is translated 'brethren' - super-archaic.

p8, 'dedicado' in 'te has dedicado a pintar?' is translated 'hardcore'.

'sí' in 'Que sí, hombre' is translated 'do', as in do-re-mi, I guess.

p5,11-12 has 'quieres/quiero repeatedly translated as "with friends like those who needs enemies". Which is just inexplicable. I can't imagine how that would happen.

Corrupted dictionary?

..and most of the trickiest words on a page aren't translated, maybe because not in your dictionary or they have 'lo' or 'se' appended.
