I noticed this missing text once I received a notification for the deed (see attachment) : first deed in the list with a 50 fame reward.

I wouldn't be able to give the steps, since the text is missing. The notification illustration is not helping as well, something related to happiness/stability maybe ? (see attachments). (edit : I understood the "locked" status as another player being awarded for a specific deed)

1/5 for now -> I'll see if it does still appear on my next playthroughs. (second playthrough gave the same result, I'll update the score with one or two more playthroughs) 

Expected text for this specific deed.

None.
