Draft Page Changes Not Showing Up In Preview

I don’t know what the deal is but it has become very frustrating. I’ve disabled caching and that didn’t solve the problem.

In particular, I have a pricing table on a page that is not yet published, just a draft, and I changed the heading for one of the columns but the changes do not show up in the page preview.

Everything is saved, I can log out, close the window, completely close the browser, open a new window, log back in, check the draft, and the backend editor has the updated text, but the it is not changed in the draft preview (and it’s not the browser cache, that’s being bypassed one way or another).

Interesting to note, if I use the live editor it shows the updated text.

Any ideas what’s causing this? Is it because I’m working with a draft?

Using latest plugin versions:
Page Builder by SiteOrigin – 2.4.25 (not 2.5 since it’s not recommended yet)
SiteOrigin Widgets Bundle – 1.8.4
