libraryID does not ensure uniqueness
I'm using symbols from 2 different libraries, one of them being 'User' type, and the other one 'Internal'. The problem is that both of them have the same libraryID, thus being impossible to manage them(identification by name couldn't be an option).
That happens with only a specific 'User' library, any other libraries don't have this issue.

Is there another option to uniquely identify and manage libraries?
Below I posted a screenshot of the JSON dumped by sketchtool.
