Equations not displaying when studying cards but it is in the editor

The Bionic Reading add-on adds a script to your template, and it can still take effect even after uninstalling it. To remove the script manually without the add-on: Open the edit screen for any AnKing note. Click the Cards button to open the templates screen. Search for _bionic-reading.js in the front/back templates. You should find a line containing something like <script src="_bionic-reading.js"></script>. Delete it and save changes.
