checkout.html changes work in development but have no effect in production

[flyingL123]

Expected behavior

If I make a change in templates/pages/checkout.html file, I am able to see it as expected when running my theme locally with stencil.

Actual behavior

After deploying the theme to the live store, I see the single-page optimized checkout as expected, but the change I made is not present.

Steps to reproduce behavior

In the checkout.html file, I add the highlighted line:

View the checkout locally and that new line is visible in the source:

Deploy the checkout to the live website, and the new line is not there:

Is there something that would cause these changes to not appear on the live site? My store is set to use "Optimized One-Page Checkout". This method of customizing has been working for me for a while. Did something change that would cause this not to work or is there a bug of some kind?
