Fonts rejected

Hi,

I purchased “proposal-brochure-template-TD52FH” and installed the fonts inside the PDF help file (Railway & Open Sans). In Adobe InDesign, Open Sans is required by another name: Open Sans (OTF), and the same is true for Railway.

I tried to fix it manually by selecting each OTF font and replacing it with the same font, but once I did that, it changed for all missing fonts the same. For example, Railway Bold applies to (Railway Bold (OTF), Railway Regular (OTF), Railway Semi-bold (OTF),…). Also, the “change” button is disabled; I can only use “Change All”. Please check the screenshot to see what I mean.

Can anyone please help? I am on a deadline!

Thank you for taking the time to read or support my message.

Regards,
Mike
