PIN figure in X2 but can't see pin figure in X3

In X2 version, after attaching a file to the reference, the pin figure will appear but I didn’t see the pin figure in X3 version.

I just downloaded X3, maybe I missed out on some things.

In the library view?  Make sure your library display setting in Edit>preferences includes the correct field name in the first column.  The correct field is “file attachments” from Endnote X onwards.  Before that, I used the “Figure” field, but you can move them from figure to File attachment so they are all in the same place, with the X3 option, References>Figures>convert figures to “file attachments”.
