Changes not reflecting in preview

Theme: Customizr
Editor: Nimble
Wordpress Version:

I have been attempting to make basic edits (i.e. reorder photo galleries, add HTML, resize/swap out images, etc) via the Nimble Editor, and the changes are not reflecting in the real-time preview or the saved draft preview link. I have disabled all plugins and am not sure what else to do from here. Anyone experienced this and know how to fix it?

Thank you!
