problem exchanging slips with Remote

I just did what I have been doing for over two years now, exchanging slips with my remotes (File --> Remote --> Exchange with Remotes).  On the first and only one I've tried so far, I got the message:

   Exchange

   The data exchange was successful.

   However, no slips were transferred because they did not match the selection criteria.

 

I've never set any selection criteria, and I don't even know where it/they would be set, and I haven't changed anything since last month.

 

Help!
