Email template changes not reflected

Hello,

I'm trying to rebrand Sisense email templates, including the social links. According to this post, things like the email messages and social links can be edited in email-templates.js, but any changes I've made are not reflected, both editing text for existing fields and fields I've added myself. They just appear blank when referenced in the header or footer files. I've tried editing both email-templates.js, and the language.js file in the emails folder, and tried rebooting the system, but changes still do not appear. Is there anything else I may be missing?
