Cannot declare class Grav\Plugin\Shortcodes\MapShortcode, because the name is already in use

I use Grav v1.1.16 and Admin plugin v1.2.12, I installed Gravstrap and various of plugins today and get this error. Still debugging to find where the problem is, so I am not sure if this is a bug of the plugin itself or a conflict with other plugins.
