This is a regression of MDL-4782 where we introduced a new mustache template for displaying status of the activity module such as "Hidden from students" or "Available but not shown on course page" in blue bootstrap labels.

The problem is that the same template is used for displaying access conditions, too. Which may eventually be quite big (see attached screenshot from learn.moodle.net site) and it does not really look good (bootstrap labels are designed for labels, not block of texts).

There seems to be no easy way to extract only the first line like "Not available unless:" and use it as a label as the renderer already receives the whole HTML formatted text from the underlying API.
