Settings doesn't show all options

Hi, I recently installed Download Manager 2.7.94

I installed the WPDM API Add on along with the iOS Add on. I needed to see the API Key for the same, but it doesn’t show in the Downloads >> Settings page. It’s supposed to be under Misc. settings I think, but that just shows Twitter Bootstrap, and nothing else. Am I missing something?
