I might be missing something obvious but I can't figure out what.
I recently installed WebStorm on my new computer and had no problem downloading TypeScript Community Stubs libraries like Angular, Mongoose etc. from the settings (I downloaded about 6 and could see the entire list while doing so).
Now, today I'm doing exactly the same thing but only get the three (see screenshot). Is anyone in the same situation? I don't think it's necessary related but I did update to 2017.1 so maybe it's something in the version...

This is due to a recent refactoring in DefinitelyTyped.
This is the issue tracking it : https://github.com/DefinitelyTyped/DefinitelyTyped/issues/15367#issuecomment-289161919
