Hi, hello. I am having this same problem, except I don't have the WPML Plugin installed. We have classes that recur weekly and I'd like to make a list of the classes, but show each only once.
I followed the advice of this thread:
and it worked when I checked right after making the change, but when I tried to add the recurring=1 shortcode to another page, the links were broken again. Curious?. Yes.
Here's link to the page that's using the recurring=1 shortcode:

If you go to the home page, you can click on the classes in the sidebar and see that the information is there:

Didn't know if the process with the WPML plugin could shed any light on mine.
