If you go Edit and click on some type Acrobat tells you the font. The problem is that it just gives the font name. If a font is in medium, book or something like that it will not tell you that information, it will only give you the main font name. So if some type is in Baskerville Book it will only tell you that it is in Baskerville.
This did not happen in earlier versions like Acrobat X Pro (10.1.16) for example. This version of Acrobat tells you the exact font and its weight, so it would say it has been set in Baskerville Book and not just Baskerville. To do this in older versions you would go to Tools > Edit, then click on a word and then Control-Click with your mouse and select 'Properties'. This tells you the exact font name, size etc. So if something is in Baskerville Book for example, it will tell you. Acrobat DC will only say 'Baskerville'.
Could you please change the latest version of Acrobat to tell you the full font name as previous versions.

Note: In older Acrobats when selecting the font you must control-click with the mouse and select 'Properties' for it to show you all the details. If you just click on some type and select 'Properties' from the main menu it will not do this.
