I don’t think so. There are a few people working in the Customizer at different times and experimenting with font changes, so it was probably just a copy-and-paste issue that caused the mismatched single quotes around the font family value in the form field.
Thank you! That helped!
I also found some mismatched characters (single quotes) in the Customizer > Fonts fields that needed to be corrected. Once I fixed that, the menu bar worked as expected!
For reference, I’m trying to get the same behavior as shown on the Agency example page here:
