Hello @lukefinsaas,
Please go to Pages > All Pages and you will see something like this:
There is a flag that indicates the language of the page. You can either Review the language (eye icon), Edit the language translation (pen icon) or Update the translation (arrows in circle icon). It means that there is already a translation page available. This is why you can no longer see the Create new translation in the builder.
If you check out the “An X Test by Rue” page, you will notice that it has the (+ icon) which means that there are no language translations for that page yet. So, if you are in the builder, as soon as you click on the flag in the upper right corner, it will ask you to create one as shown in the screenshot above.
- See the secure note below.
What you can do to the existing translation pages is if you want to use the builder, you can save the sections as a template and then use that template to create those translation pages.
Best Regards.
