Touch ID not working on Numbers spreadsheet (otherwise OK)

Numbers displays "Open w Touch ID" checkbox checked, as it is, has been and should be.

BUT the Touch sensitive Control Bar on the MacBook Pro DOESN'T present the Touch ID Arrow to the Power Button.

Touch ID functions for other applications.

Mac OS just Updated today.

Tried to turn Touch ID OFF, then ON... and restarted MacBook - but doesn't solve my problem.

Please help and Thank You too!
