Why is a resource shown both under 'meeting room' and 'other resources', and how can this be corrected?

When a resource, such as a boat, appears both under 'meeting room' and 'other resources', this is probably due to an incorrect configuration, where the resource has been assigned to several categories. To fix this and have it under only one category, the system administrator needs to adjust the resource's settings. This involves removing the resource from the unwanted category and ensuring that it is only associated with the desired resource type, e.g. only 'meeting room'.
