We want to show only translated posts in Spanish but fallback to English for other secondary languages.
Solution: If you have your posts set to Translatable or Fallback to default, then any post in any secondary language that does not have a translation will show English. From what I can tell, the posts that are showing on English on this page do not have Spanish translations. So it is working as expected with the Fallback option. It is not possible to set some languages to fallback and not others.
