This isn't a "by Roll20" sheet, meaning that they don't maintain it. It was created by the community, meaning that you can find it on the Roll20 character sheet github repository. Each sheet has a sheet.json in the folder, which lists a Roll20 user ID for the author. I believe the author you are looking for can be found here: <a href="https://app.roll20.net/users/46544/ada-l" rel="nofollow">https://app.roll20.net/users/46544/ada-l</a> I believe the issue is that they just did an update to the sheet.json and forgot the legacy switch, and so the css isn't rendering correctly.
