In Analysis Service we generally see all dimension has All member. This is because of the IsAggregatable property of the attribute. You can set its value to false so that it will not show All members. It's the default member for that attribute.
If you hide this member then you will have to set other attribute values to the default member else it will pick some value as default and this will create confusion in browsing data if someone is not known to change in default member.
