You have entries that either have no dash "-", or have one but nothing
after.  You can NilClass#puts, but not just any method on it, such as
#capitalize.  If you don't need them (like, for example, counting
purposes), remove your nils out of the array list with #compact.
Example in irb...

[1, nil, 2].compact
=> [1, 2]
