Hi Allison,
Thanks for posting and I’m sorry to hear you are experiencing difficulties.
Enfold ships complete with a number of customizations that target our own plugin. As part of this, they restrict/remove access to certain settings and I suspect that is what you are hitting up against here.
This can easily be confirmed by quickly switching to a default theme such as Twenty Fifteen – you should then see that those settings become accessible. With that in mind (unless you find the same problem does still occur when you perform that test, in which case the issue may be something else) I’d recommend approach Enfold’s support team for assistance.
