It’s not the first time I notice there is display problems in the outliner. So I decide to take a screenshot :=)
In general it’s impossible to see the last column (last displaying option activated) entirely. Instead to use the scrollbar. To remedy of that I usually select another displaying option I don’t need. Its creates a new columns, so the last column become not the last one
Well, I’m not sure to be clear… But see the screenshots below.
