displayed packets unmatched when trying to export

edit

Hi,

I notiched that the # of displayed packets is not the same as it should be when you try to export them, please see that screenshot below:

Is it a known isssue? I was using "smb || smb2" as the display filter.

i further confirmed that the smaller number contains only smb/smb2 packets, while you try to export, the larger number also contains the pure tcp packets (for smb file streaming) for the corresponding smb session. Is it expected?
