Please check if the filter.xml is configured as required under ui.content\src\main\content\META-INF\vault - e.g
<?xml version="1.0" encoding="UTF-8"?>
<workspaceFilter version="1.0">
<filter root="/content/emailtemplate"/>
<filter root="/content/dam/emailtemplate"/>
</workspaceFilter>
If the mode is enabled, ensure the appropriate value is configured
e.g
<?xml version="1.0" encoding="UTF-8"?>
<workspaceFilter version="1.0">
<filter root="/content/emailtemplate" mode="merge" />
</workspaceFilter>
"replace" - This is the normal behavior. Existing content is replaced completely by the imported content, i.e. is overridden or deleted accordingly.
"merge" - Existing content is not modified, i.e. only new content is added and none is deleted or modified.
"update" - Existing content is updated, new content is added and none is deleted.
The default filter mode is "replace"
