New plugin installation - 80+ machines showing as 'installing' without having been pushed

Just as the title says, we just enabled this plugin, and have only pushed out to a total of two machines using it since we set it up two days ago. Yet I have 87 machines in the plugin showing 'installing' for the deployment status. They've been like this for two days. We did not push manual installs, and the locations are not set to autodeploy - they just appeared this way.

What info are they pulling that populates this field? How can this be fixed?
