Okay after some very frustrating repeat failures, I think the problem was with a bugged save.

The "tab' was present on my first attack attempt but when I reloaded to try and practice again it became very hit or miss if it became present.

( I assume since its a 'window' of sorts it somehow became stuck 'off screen' somewhere.)

Restarting the campaign has (so far) seemed to resolve the issue.
