Cannot search users

I had to transfer my website, so I used a plugin to download the users as a CSV and another plugin to import the users back in. Honestly, there were bugs and everyone’s password had to be redone.

But besides that (This is where my question come in), I cannot use the search feature to look for a user. It only can find the admin profile. are the users not in the data base because they were just imported in? Any idea how to fix this? Thanks!
