New Added Attributes- Select Entities

I am a new user on Space Design and having problem on editing the attributes. After i created my own attribute for my components. The file is saved and export to .csv report which is good also. Then I tried to use the "Select Entities by Attribute Value" from the tool bar to list the attribute. However, the list of attribute is exactly the same as the original. Did I skip any important procedure to update the those attributes or that "Select... Value" is not supposed to list our own attribute?
