Front end form no longer showing existing data to the logged in user

I have a site which has been working well for over a year.

User logs in, enters data to their profile, and with Front End Admin can come back and edit that form showing the already added text.

But now the data has gone from the fields!

the code to populate data is

$profile_id = um_profile_id();
echo do_shortcode(“[frontend_admin form=**** user=’$profile_id’]”);

*being the form id

ACF group (containing multiple fields) is used in the front end admin form.

The page I need help with: [log in to see the link]
