# Data Edits

##### **I edited the Room Number in Contacts, but it doesn't show up on Reports.**

When a class file is imported, teacher data is copied into the resource section on the **Appointments** page. After that, this copy becomes independent — editing the Contacts section will **not** update it.

**To fix a single teacher's room number:** Go to the **Appointments** page and edit the room number directly, in the field to the right of the teacher's name.

**To update room numbers for all teachers at once:**

1. Import the **Teacher file** with the updated room numbers.
2. Import the **Class file**.

This will update room numbers for all individual teachers on the event.

<p class="callout danger">Importing a Class file overwrites manual edits. If you've made manual changes to a class, update your Class file to match before importing — otherwise those changes will be lost.</p>

> **Note:** This bulk-import method does not work for **Teams of Teachers** — room numbers for Teams must be edited manually.
