Search Bar Stopped Working

Hello there, I was given this website as the former person left the community it was made for. Awhile back ago, we noticed that the search function for our applications just randomly stopped working and I’ve finally sat down to see what in the heck happened because no one has touched it. The first screenshot shows the search function. You’re supposed to type in the Discord name specifically to get the pop ups and just do it TWICE and it worked in the past. Now nothing pops up. The second one shows what the search box is going based off of. Any ideas on how to fix this??
