Hi Momchil,
It sounds like you have two web fonts in your prototype–Open Sans and Open Sans Condensed–and you’re finding that Open Sans Condensed Bold is falling back to Open Sans Bold. Is that correct?
As a first step, please go to “Publish > Generate HTML Files > Web Fonts” and make sure that you have two separate .css links with their proper font-weights, one for Open Sans Bold and another one for Open Sans Condensed Bold:
If that hasn’t been set up yet, you can grab the .css links from Google Fonts, here:
Open Sans Condensed Bold
Open Sans Regular, Bold
Feel free to also take a look at my sample RP file so you can see the setup of my webfonts. Hopefully it helps!
