Hi!

Thank you for caring, I see the problem when I plot the drawing. While I am working on AutoCad it appears without problems. 

My Mac Version is: Mojave 10.14.2

Autocad 2017

And the screenshot with the font info (The Helvetica Neue has the two typefaces I'm using: Condensed and Bold)

I attach the drawing too, the problem is on the layouts (the names are: A10 - Situación y Emplazamiento and Para bocetar), on the title block I'm trying to make.
