I've downloaded one adm file corresponding the the classic track of Reader DC. I've then create a new group policy and loaded this template. The computer section of the group policy shows up fine. However, the user section of the policy shows the subcategories (ie General/Security) but the end nodes of the policy do not show anything that can be configured. Please see attached picture:
For example in this category, it should show the "Automatically trust sites for Win OS security zones".
