Did you deploy the changes to the XSD on all farm members and issue an iisreset?

Does this subsite have a custom deployment?

As far as I know, custom settings cannot be exported and imported.

Just want to find the way to reset the custom setting to default & doing the Import-SPWeb(Export-SPWeb is OK without error)

Hi Trevor Seward:

Have already follow you Blog guide to check the "DeploymentManifest.xsd" file, It have the parameter "<xs:element name="ColumnWidth" minOccurs="0" maxOccurs="1" />" by default. My SharePoint 2019 version is RTM(16.0.10337.12109) & is Single Farm.

There seems to be no quick way to restore the default configuration, you can only manually restore your custom content to the default.
