I have a class for handling customizer code, where I am adding a lot of color options. I have trimmed a bunch of repetitive parts out so it is not too long ;) My issue is I cannot figure out why the default settings do not appear to be being set, but only on front end. If I open in the customizer view, the live preview is correct, the defaults are working, however on the front end view it is not. If I change a value in the customizer to hit save/publish, then the front end looks right. So this leads me to think the defaults are not being set like I think they are, hoping for some help figuring out why. Thank you.
