Following the instructions for creating a translation with WPML, I go into the Pro editor, click on the flag in the bottom right corner, then create a clone from the English page. The new page for the selected language is properly created, however Pro is never able to render the page for editing.

This ONLY occurs on pages that were created by going through the flow of creating a new translation from within the Pro editor.
Currently running WPML 4.3.10 and Pro 3.2.2
