Why does Project Change duration when adding resources?

The duration, work, and resource assignments for a task are interlinked. When you assign resources to a task, Project calculates how long the task is likely to take to complete using those resources. If you assign multiple resources at the same time, the duration doesn’t change from your original estimate.
