Layout options default

When I import xml files , I always have the problem, that Dorico chooses some settings, which I don’t want. E.g. to show the shortnames of the instruments on every line of the score and a part header. So, how can I get rid of them? It doesn’t help to choose these settings in the layout options and save it as default . Dorico just ignores it , when I open another xml file.

In general, deselect every option in Preferences>MusicXML import options and Dorico will do its best to lay things out as per its normal settings.
