Missing Smart Scan Title

Hello, I am not able to see where the Smart Scan title is showing. It appears to be be missing. Should be under “Look at the Avast UI > Protection > Virus Scans > Custom Scans - Smart Scan … (three dots menu) Settings.”
All I see are Full Virus Scan, Targeted Scan, Explorer Scan, and Boot Time Scan.
Smart Scan definitely is there somewhere and works since I just got an automated scan result from it. Thank you.

It should be there on the main UI Home Screen.

Try an Avast Repair - UI > Menu >Settings > General > Troubleshooting > Repair APP.
Restart your system after the repair.
