While executing a **[System Health check](https://community.novulo.com/t/system-health-in-novulo/111)**, Novulo validates user overview settings to identify which users have corrupted grid columns or references to grids that no longer exist.

Navigate to:

**All apps \> Settings \> System Health Checks \> System Health Check \> User Overview Settings Health**

The **Show all** checkbox (default = no) loads all user overview settings, not only those containing errors. Clear the **Show all** option to display only the settings with errors.

In the dropdown next to it, select **All users**. You will see any detected errors together with the following buttons:

- **X – Delete**  
Use this when the error contains the message “_null_”. This removes the affected grid or grid column for the particular user.

- **S – Save**  
If you click on the corrupted expression, it becomes editable. After editing an expression, click **Save** to keep your changes. **This button is only visible when a text value is being edited**.

- **R – Reload**  
After making changes, click **Reload** to verify whether the issue has been resolved.

For example, if a grid no longer exists, you will see an error such as:

Click **Delete** to resolve the error.

**Corrupted grid column errors** usually indicate that a column references a property (field) that has been removed or changed. You can fix such erorrs the same way you can fix the expression field error.

First, check the data model ( **Expression Debugger \> Data Model \> Data Type** (table name is visible in the error description as type handler) **\> Field** ) to verify whether the referenced property (field) still exists.

In the example bellow the field “is\_reversal” was renamed to “is\_chargeback”:

In errors like this you can either:

- Update the reference from the **User Overview Settings Health** page (click on the expression and edit it) and then click **Save** and **Reload** , or
- Remove the affected column from the grid.

> **Pay attention to which X button you click**  
> Clicking the wrong **X** may remove not only the corrupted column but also columns that are still valid. If you only want to delete corrupted column, use the **X** on the right side at **column level** , not the **X** on the left side at **grid level**.
