Paste only the layers of the first master

Hello, I am using Glyphs2.
There are two masters in my file.
When pasting smart components, how do I copy and paste only the layers of the first master(All layers included in smart components)?

At this time using ‘paste special’, all layers of the 2 masters are pasted or only the contents of the active layer of the first master are pasted. I really want to know…Any solutions?
