Record first appears then disappears from screen

i have a simple app that enables musicians to find and jam with other musicians and view public jam sessions.

jams are stored in ‘meetup’ table. table has a public flag (true/false) and an organizer (which is a user).

when i login and system display Home list, system presents the records i expect to see: one where the logged in user matches the meetup’s user and one where the record is ‘public’ (ie meetup.public = TRUE). this is expected behavior

then about 5-10s later then record that matches on user disappears and only the public meetup is displayed. any ideas on why?
