I have reproduced the bug with the Direct to backend function, but cannot see why the Enhanced with DFFS link should be hidden. Can you check the console (F12 > Console) to see if you have any errors there?
I’ll fix the bug with the Direct to backend as soon as I can manage, in the meantime you can change the end of the URL from:
&defaultLoader=false
to
&defaultLoader=true
and reload the page.
