Id macro is not imported properly

When the confluence page has anchors within the page, the macro is not having the id attribute.

After importing the confluence page, I see this error in the imported page - 

Invalid macro parameters used for the "id" macro. Cause: [Property [name] mandatory]. Click on this message for details.

And the stacktrace - 

org.xwiki.properties.PropertyMandatoryException: Property [name] mandatory at org.xwiki.properties.internal.DefaultBeanManager.populateBean(DefaultBeanManager.java:178) at org.xwiki.properties.internal.DefaultBeanManager.populate(DefaultBeanManager.java:109) at org.xwiki.rendering.internal.transformation.macro.MacroTransformation.transform(MacroTransformation.java:287) at org.xwiki.rendering.internal.transformation.DefaultRenderingContext.transformInContext(DefaultRenderingContext.java:183) at org.xwiki.rendering.internal.transformation.DefaultTransformationManager.performTransformations(DefaultTransformationManager.java:101) at org.xwiki.display.internal.DocumentContentDisplayer.display(DocumentContentDisplayer.java:263) at org.xwiki.display.internal.DocumentContentDisplayer.display(DocumentContentDisplayer.java:133) at org.xwiki.display.internal.DocumentContentDisplayer.display(DocumentContentDisplayer.java:58) at org.xwiki.display.internal.DefaultDocumentDisplayer.display(DefaultDocumentDisplayer.java:96)
