Column for track and category are sized too small to display their titles

It's not a huge issue, but thought I'd mention it— the columns for "track" and "category" (guessing it is category, since it is mostly hidden) are not resizable and their titles are not visible, other than the first letter or two.

Looks like all titles are visible here... What version of Mac OS are you experiencing this behavior on?

D = Division
F = Format
T = Tracks
C = Channels
