Hopefully no-one has reported this yet, I have no idea how to do a successful forum search for this.
In the People credits overview, the number of entries shown is limited to 4 per role. If there are more entries, this is shown with a double down arrow and the text View # more, which you can click to show the rest. This usually saves space, except for when there are exactly 4 appearances. This creates 3 lines plus "View 1 more", which when clicked takes up more space then the original 4 would.
Example: the Borg Queen entry for Susanna Thompson
Should be easy to fix, probably just a missing = sign in the code or something :)
