The shortcode looks correct. Please make sure the program name is exactly the same as in Wodify (case-sensitive). Please look up the exact spelling in your Wodify calendar – or even better – in the dropdown of programs in the general WPWDFY plugin settings.
I have tested this with my tenant again and for me it works. The strange thing in your scenario is that you seem to get the default program’s WOD – not sure why this happens – if the program name is misspelled you should get “No WOD”.
Just to make sure there is no caching problem please add ?updatewodcache to the URL where you try to display the WOD.
If all of this does not help, I will have to create a plugin version with some debug output for you.
