"Manage Lookup Engines..." Disappear

Report ID: 73434626

After I click the "toggle" button in the Article Lookup Engine Manager window, I can NOT find "Manage Lookup Engines..." option and my customed search engines in the "Locate Menu". So I can not use my engiens anymore:(
All my customend engines codes are still in the .json file.

Steps to reproduce:
1. Start Zotero.
2. Click on "Locate Menu" ——the straight arrow button (→).
3. Click on "Toggle" like three times.
4. Go back to main window, when I click Locate menu, the "Manage Lookup Engines…" is not there.
5. Restart Zotero.
6. Still not there.
