Hello Soyab,
Sorry, I misread your posting earlier.
May be this problem is because SAP does not checks for all published application objects whether there are attachments or not. To fix it
1) In TC->SM 30 use the table SXPARAMS.
2) Create new Parameter: GOS_ATTA_CHECK_ALL with Value: X
This should display all the documents. Please go through this post to have clarity.

Please post if it doesn't fix.
Thanks,
