@tr.roznowski, I agree, without being able to see more it’s impossible to say what the issue may be.
The only ‘obvious’ thing would be if you haven’t deployed your app to ‘live’ since setting the data for the search box, otherwise there must be something more complex going on.
If you post a link to the editor (read-only) on here I’ll be happy to take a quick look for you to see if I can figure it out.
