Thanks for the .rp file! I see the issue now.
It looks like you're using several different font weights for the Source Sans Pro web font in your file, but only the Regular font weight (400) has been defined in the CSS link.
To remedy the issue, you'll want to select all the different font weights you used in your file on the Google Fonts site by switching over to the CUSTOMIZE tab:
Then, switch back to the EMBED tab to copy the updated CSS link:
Which you will then want to copy & paste into the Web Fonts tab of the Generate HTML dialog:
I've applied these changes to your file. Lmk if you have any questions.
