After playing around with many new views and creating the template for the output/results/loop, and then deleting these new views, I find I am left with loop templates that no longer are attached to the views because the view has been deleted. Is there any way I can clean up the loop templates?
Solution:
You can trash/delete the post views, then all content templates in the view's loop will be removed too.
Solution:
User did not translated the taxonomy using WPML correctly. What you should do actually is that you should add all Category names in English and then translate all those categories in your secondary language.
Should I always create the Content Template first, then various View(s) to place the Content Template shortcode, and afterward add Content Template(s) into a View(s)?
Solution:
If the content template will be used in only one post view, you can create the post view first, and generate the content template automatically.
If the content template will be used in multiple cases, then you can create the content template first, and display the content template shortcode in where you want, for example
